Bill Bryson wrote an excellent, funny book called I'm a Stranger Here Myself, all about America and the new meaning it took on for him upon his return after 20 years in Britain.
The introductory excerpt spoke to me, made me giggle, and dropped a bit of nostalgia my way:
As well, there has been the constant, unexpected joy of reencountering all those things I grew up with but had largely forgotten: baseball on the radio, the deeply satisfying whoing-bang slam of a screen door in summer, insects that glow, sudden run-for-your-life thunderstorms, really big snowfalls, Thanksgiving and the Fourth of July, the smel of a skunk from just the distance that you have to sniff the air quizzically and say: "Is that a skunk?", Jell-O with stuff in it, the pleasingly comical sight of oneself in shorts. All that counts for a lot, in a strange way.
