oxycodone vs hydrocodone. One is an effective pain reliever for me , the other does nothing. I can never remember which is which. Maybe if I had surgery more often…
This.
There are usually three elements at play here that I have a hard time remembering (country, which is the majority, and which is in power). For each country, you need something like this.
In (country), the (Sunni/Shia) are the majority and the (Sunni/Shia) are the minority. (Despite/because of) the fact that the (Sunni/shia) are the (minority/majority) they are able to rule the country and lord it over the other faction. Be cause the (Sunni/Shia) are in power for (country), they are usually more supportive of (second country with similar sided power) over (country over opposite sided power).
You don’t need to, they’re already labeled. Open them wide, with the thumbs sticking out, and the one that seems to have the thumb make an L with your index finger is your Left hand.
I am grateful that I have no *need *to distinguish the Guelphs from the Ghibellines, except when navigating southern Ontario and possibly not even then.
But … When you do that you’ll notice there are 5 fingers on that hand. Five being the number of letters in the word “right”. So that hand is reminding you both that it’s the left with the ell-shape and that it’s the right hand with the counting up to five letters. Now we’re confused again !!! 
Palm up or palm down?
Which side is the palm?
Left.
But what if I’m facing South?
^^ Then your toilet flushes backwards.
Oddly enough, I went through my entire schooling career never having been taught that poem, so I never know how many days are in a month either.
Luckily, they make these things called “calendars” these days, even if our esteemed doctor can’t spell the word.
Oh, those are both quite brilliant. 
Alright, I’ll return the favor: re-write the sentence to use he/him, which is usually easier for native speakers to do intuitively:
You went to the store with whom? = You went to the store with him?
Who called you? = He called you?
etc. etc. etc.
I accept payments in cash. 
I take exactly 5 roads to get to school every day, but is some were to ask me right now what those roads are, I would only know 1.5. The .5 is because I know that one road eventually becomes Colerain Avenue.
Names. of people and roads.
If I have to give directions, I have to do it by landmarks, the names of the roads just don’t stick in my head.
Same as people. I have 30 people sitting outside my office and after several years I can now remember most of their names. If you say the name of someone I’ll know who they are straight away, but i have a mental disconnect between what they look like and what their name is. I’ll remember a name and remember a face, but struggle to keep the two linked.
If it were the case that a dromedary wasn’t a camel, you would have the following mnemonic, which Ogden Nash only wished he could have written:
The one-hump camel
Don’t exeest.
The two-hump camel–
There’s a beast!
And I’m sure you’ll all
Agree there damn well
Better not be no
Three-hump camel!
Logarithms - I was always good at math, Algebra, Geometry, and Trig were easy, but I hit a brick wall when it came to logs. I didn’t then, nor still now, have any clue what they are or what they do. And don’t want to.
If I am introduced to two people at the same time, I will forever mix them up. In fact, forget “people;” if I learn two *facts *at the same time, they get merged in my brain. I refer to the phenomenon as robandjohning, since I first figured out that I do this when I was introduced to - you guessed it - a Rob and a John at the same time. They were roommates, and buddies with the crowd I hung with at the time. So we’d just say “Hey, let’s go to Robandjohn’s place” and I simply never figured out who was who.
I come from a family of fair geniuses in math who have absolutely no sense of direction. I tell people the reason we grew up in Boston is that our ancestors got off the Mayflower and never found their way anyway else. I get lost in the town I’ve lived in for thirty years!
“A log is an exponent”. I was told this in college algebra and it seems to have stuck with me with regards to the use of it.
You know that probably doesn’t help you much…:smack:
“A log is an exponent”
I’m laughing so hard at this statement - maybe that was my problem in High School.
I refuse to remember whether the proper spelling is ‘accommodate’ or ‘accomodate.’
Also, anything involving liquid measurement: quarts, pints, ounces, hogsheads. It just goes in one ear and out the other.
