Yikes! So everything inside those boxes are in Belgium? Some of those look to cut through buildings … diagonally!
Have you noticed though, how many people from the Republic won’t venture up North even still? Because of family connections I’m in Norn Iron about once a month but I have friends who’ve lived in Ireland 30 years and never set foot north of the border.
No, it wasn’t.
There are houses (and shops?) that straddle the Netherlands/Belgium border. What country’s taxes you pay is determined by which side of the border your front door is! 
A handful of European countries also have small enclaves located entirely within a neighbouring country’s territory. If I remember rightly, this also occurs along the India/Bangladesh border. I doubt any of these places have any sort of border controls.
So, what happens if a US citizen goes to Canada, forgets their passport, and is allowed to enter Canada? Are they just stuck in Canada forever since they have no passport?
Indeed, there is an Indian exclave called Dahala Khagrabari which is inside a Bangladeshi exclave which is itself inside another Indian exclave inside Bangladesh.
They’re ours! We put them to work in the snow mines!
I’m gonna say the UK and Ireland: most of the laws in those countries don’t regard people from the other as ‘foreigners’ or ‘aliens’.
And UK/Irish citizens can vote in each other’s general (national) elections.
Canada and the US have nothing so tight.
Wuh? I am British and I most definitely cannot vote in an Irish election, what with it being a foreign country and all. I think there might be people who are citizens of both countries and therefore maybe can vote in both places, not sure. But the laws of each country do not apply to the citizens of the other (again with some possible exceptions relating to Northern Ireland).
The two countries do have a lot in common culturally, true, and a generally warm relationship with each other these days. I do vaguely remember there being some kind of tension between us in times past, though. 
False. If you moved to Ireland tomorrow you could register to vote in the next parliamentary elections. Similarly for Irish citizens resident in the UK. Cite. The same is not true of other EU countries.

At best, cautioned to not do it again, and let in the country.
Usually, turned back at the border or not let on the plane in the first place until they have their passport sent to them by family or friends, or order up a new one via a consulate.
At worst, rendited and tortured.
There was a news story this week about President Obama saying something about wanting the US to import most of its oil from Canada and Mexico, instead of the Middle East, and my response was, "Huh? I thought you were already doing that, since Canada is the number one oil supplier to the US." Enjoy all that dirty Tar Sand Oil, US Americans! 
Well well, I did not know that. I did think there was maybe some kind of provision for people in NI voting in Ireland and/or vice versa.
Try spending Scottish ounds in London though. 
You have it wrong. It’s Canadian citizens, going through the USA and WITH THEIR PASSPORTS, who get that treatment.
The Canadian government settled with him, and paid him a substantial sum - ten million. The US government, last I heard, was using “it’s top secret” to try to keep the case out of the courts and still insists he’s a terrorist and he’s on their no-fly list.
I believe its also pretty simple for citizens of the Republic of Ireland to join the UK armed forces, not sure if this arrangement is reciprocal though.
I would describe the relationship between Ireland (North and South) and that of the rest of the UK as that of close cousins, said closeness being the reason why any disputes there are tend to be so intense and personal.
I knew of Irish citizens serving in some of the most hated (by republicans) units of the British Army in N.I. during the troubles.
I think that its unlikely that a Brit could join the Irish forces because they’re so small.
(Though I don’t think that it is legally prohibited in Irish law)
That said the British Army has trained some elements of the Irish Army in recent years.
The Rangers for one.
Yes, I never crossed the border into Norn Iron until I was in my 30’s. I always saw it as a foreign place, whose people had grown away from us over nearly a century.
I hated the rampant sectarianism in NI, which poisoned foreigners’ view of my own country - the Republic of ireland. Sectarianism exists in every country - poke a lot USAians with a bit of Islam, and watch the reaction. However, sectarianism was not a major factor in daily life in the Republic.
It was not just the unionists. I was more scared of the people who purported to be nationalist Irish, and flaunted my country’s flag as a sectarian, divisive symbol. They still do it at elections, to my disgust.
Now that the IRA has stopped stirring up hatred and dividing people, we have a chance to meet people on normal terms.
Think of it as siblings. Siblings in the back seat on a long car trip. Of COURSE you have to pick at each other, but that doesn’t mean you hate one another, really, right?
Norway and Sweden love each other so much that Swedes generally tell the very same jokes about Norwegians as Norwegians tell about Swedes 
Actually all the Nordic countries have a love/rivalry relationship with one another, just some pairs more than others. (See the webcomic Scandinavia and the World for more information.)
When I was in Denmark they commented on their closeness with Swedes,but couldn’t help mentioning how “carefull, if you know what I meanl” the Swedes were with their money .
I mentioned this in Sweden and they said that was actually how mean the Danes were.
But to be quite honest neither can be as miserly as the Scots who,when it comes to paying out money,are tighter then a ducks arse.
I’m surprised to hear this. I’m and American from the Detroit area and I and my wife have driven over to Canada at least 7-10 times(once per year or so) since 9/11 and have never had to give our passport. In fact, for us, it’s the same as it used to be.
Here is our experience re-entering America. We are not Canadians, mind you.
Now in 1995, we went with my Uncle from England. We pulled over and he showed his passport. Took about 15 minutes or so.
I guess maybe today it might be harder to get a English guy into Canada, but not by much, I should think.
*OK, they didn’t say “eh”, but I need at least one joke.
