A few observations

1. When I am very, very tired and having difficulty understanding someone's accent, I tune them out so that it all sounds like Charlie Brown's teacher. "Den I was loike, sumfing wah wah waaaaah wah wah wah...."
2. I live in lilliput. I know i've been over this, but damn, it still shocks me!
3. Even if you are very, very, very careful to look in what you think is every potential direction before crossing a road, you'll probably miss a hazard. I have, for the record, been honked at by several (as in I stopped counting) cars, one tram, and two busses. Not bad for two and a half weeks.
4. Brits are all alcoholics. Binge drinking aside, when I pass a drink off at the 'bux, 90% of people pick it up, bob their heads, and say 'Cheers'. Then I noticed bus passengers doing it too...and at the supermarket (what I was missing?!), and on the street when I gave way to an old lady with a walker. Wtf?! Cheers is used interchangably with 'Thanks' here, but never in sarcasm and only when there has been a service of some kind rendered. I think.
5. The legend about Europeans being apologetic if they accuse you of being American and you are, in fact, Canadian? Totally, embarassingly, true. I'm working at the espresso bar, chatting and calling drinks, and I hear a mother and teenage daughter arrive at the register. "I TOLD you it was an American accent!" (other barista) "Oh, actually, she's from Canada." (woman now shouting across half the store) "I'm so SORRY dear, I guess it's just loud and difficult to hear properly, and I am VERY SORRY" (me, being uncomfortable) "Oh, it's ok, I can't tell as Welsh accent from an Irish one, so how can I expect you to tell mine from an American accent, eh?" (woman smirks).
6. Brits are adult enough to decide when and where to cross the road. Jaywalking doesn't exist here, because it is legal to cross the road at pretty much any time. However, pedestrians don't automatically have right-of-way. See #3.
7. There are more things that I want to put up here, but i can't remember them at the moment. Some day, some day.
