Hmm . . .
The money's all the same size . . . There's a one-dollar bill but no two-dollar anything . . . tax is not included in the stated price and you have to tip your waiter.
People are driving around on the right side of the road.
There are people who are interested in baseball. And American football.
There is not a steak and cheese pie anywhere in the vicinity, but I can go to Taco Bell whenever I want.
There are American accents everywhere.
Must be home!
(As a matter of fact, I've been home for two days now, but I've been too lazy- at least partially connected to jetlag- to say anything about it.)
