It was my birthday on Tuesday. My in-laws aren't very thoughtful people at the best of times (On DH's 30th birthday last year FIL only spent a tenner on him and he isn't hard up) but I always get at least a card from FIL and various other family members on my birthday.
This year I didn't get a single card, and the only text came from FIL who said he'd bring my card 'when he sees me next', when he doesn't come to us much - the last time he did was Xmas, but we do go up to see them all every 6 weeks or so. We always send birthday cards to the in-laws so we do reciprocate.
AIBU to be a bit upset? DH didn't seem that bothered when I pointed out to him that I hadn't had a card.
