Ugh, I wanna vent, too!
I have an uncle who completely ripped apart our decision to live in the UK instead of the US. He referenced everything from the size of refrigerators and gardens/yards to the myth of me having to give up my American citizenship.
The only thing that I seemed to be able to argue with was that the pound was stronger than the dollar and I could pay off my student loans quicker living in the UK. My slight Anglophilia, academic background and interest in European history, as well as husband's UK based band and job he loved didn't seem to sway his opinion that living in America was the better choice for us.
My father doesn't really understand why we're living in a "dump" (perfectly adequate top floor one bedroom flat) when for the same money we could have a house on a 1/2 acre in the states either. Of course, he doesn't understand why I went to university either.

*sighs*
Done now. For the moment.
