I come from a family where it is expected that the women do everything (very few women in my entire family work ft, but me working ft doesn't seem to get me off the hook) and have ILs who 100% think it's my job to do all cards etc. (MIL once slapped me because I forgot her anniversary.)
When I started moaning about it to DH, he said he hates the ridiculous cards/presents stuff so didn't want to do it. As a test of his veracity, I just stopped doing it, to see if he'd get cross with me (LTB), not do it (He's lazy but honest) or start doing it (had been leeching off me). Turns out he's lazy but honest. I decided it was the way to go, so now we do NO gifts to extended family and a max. of 10 cards.
Which leaves us with time and money to spend on ourselves! Result!
I really do think the number of people who buy gifts for cousins etc, and send about 100 cards is quite gross, actually. I'm much happier with a scaled down, less stressful time.
