I'm quickly learning that my future in-laws go pretty nuts with the Christmas shopping too. My family's always been fairly tame with the shopping, but with a new fiancee in my life this year, I'm seeing that she might be looking to spice things up just a little. I'm just glad that she's handling 90% of the shopping, since that whole chore gives me a major headache.
There have been rumblings from a few poeple in my wife's family about changing to a partner type system, where you're only buying for one other person instead of everyone. But I highly doubt that will actually come to fruition.
We have been spending a lot more than I'm used to on Christmas decorations for around the house though. I guess as a former bachelor, stuff like that wasn't such a high priority to me in the past. But whatever keeps my girl happy now!
