As a British-American, I often fall into an uncomfortable middle. I still pronounce 'schedule' and 'water' like a Brit, but I say 'y'all' as well. My accent tends to change based on who I'm listening to. Most of the time, Americans can't tell I'm British. So long as I don't say a specifically British sounding word(like schedule), my accent is typical American. But if my mom calls me up on the phone, and I hear her accent, I almost immediately switch to a British accent.

This was something I'd never really noticed until my roommate pointed it out.

We've been watching some of the new Who recently and apparently I've been stuck in British-accent for the last week.

It's funny, because ALL the things you listed above? I use the American versions of the words, because I've lived here for the last twenty years, and the first time I saw a cell phone was in America, and so I learned the American term for it. But at the same time, ALL my friends still point out all the Britishisms I use in speech(and usually playfully tease me for them). When I'm in Britain I'm seen as a complete American by all my relatives, but when I'm in America I'm seen as a Brit!

I can't win! Also, I can't give blood in America because I might have THE MAD COW OH NOEZ and I can't give blood in Britain because I might have THE WEST NILE DEAR GOD.

At least the British have the justification that the disease can be spread by blood, and it has killed more than like...a handful of people in the history of ever. But still. It's very irritating, especially because I have a rare bloodtype, and even though I'm perfectly healthy, no one wants my blood :(
