Silly Americans, thinking that sewing a maple leaf on your backpack will let you pass as Canucks. Harrumph. Don’t you know that we have a secret badge that identifies us as Canadians to other Canadians? You will be caught out and stomped 
(This is actually true-- It’s how I was identified as a Canuck during my recent jaunt to Europe.)
Anyways, back to Paris. Parisians, like everyone else in the world, are totally polite as long as you make the attempt to speak in their language first.
Don’t eat at McDonald’s if you can help it. You willhave a tough time finding somewhere to eat between 2 and 6 o’clock, though.
Dinner (the good ones) starts around 7:30. Do your day stuff, then go back to your hotel and take a nap, then go out to eat and spend the night on the town.
Places to see: The Arc de Triomphe has a ceremony every evening at 6:30 where they relight the eternal flame.
The reason Cliffy was stuck at the top of the Eiffel Tower is that you can’t walk down from the very top. The stairs only go up to level 2. I do recommend taking the stairs up that far-- there’s lots of neat reading on the way up.
If you’re into science, go the the Pasteur Museum. He kept everything that he ever worked on, the museum is his actual house, and hardly anyone goes so you’ll pretty much have it all to yourself. It only takes 60 minutes or so to see the whole thing.
My other preferred museums are the Musee d’Orsay, and the Musee Rodin. Go early, because the crowds get pretty bad (although I was there in May).
Did you know that there’s a gladiatorial arena in Paris? It’s in the Latin quarter, and called Les Arenes de Lutece. Not much to see (other than to walk around an honest-to-goodness Roman era piece of architecture) but it’s tres cool if you’re into that thing. Good place for a picnic, but not really worth a special trip.
Les jardins de Luxembourg was really nice in May-- dunno what it’s like in November.
I only caught one real piece of nightlife, La Caveau des Huchettes. Live jazz music in the basement every night, but you better bring your dancing shoes.
Bon Voyage!
