four london thoughts

1. i can't figure out if i'm supposed to walk on the left side of the sidewalk (since cars drive on the left) or the right. everytime i walk on the left, i run into people. everytime i walk on the right, i run into people.
2. guys here don't wear undershirts under their button downs. not sure what that's all about...do they know that some shirts are kinda seethrough?
3. older women here all have mustache/beards going on. they're not super long, but the hair is definitely dark and course enough to notice. is it acceptable for men and women to have facial hair here?
4. haven't seen anybody with horrible teeth. maybe it's because i'm in london...and the british with bad teeth are in the outskirts.
