Things I just can't get bring myself to get too upset over now that I've lived in Europe:
1) Public nudity, including, but not limited to, Janet Jackson's right one.
2) The price of gas. (I complained at first, but now know that a few cents per gallon doesn't make a difference unless you drive a lot of miles per day in a gas guzzling vehicle.)
3) People who may or may not be under 21 being exposed to the idea that alcohol exists.

Breathe, America, breathe.
