I don't 'do' cards (birthday, wedding etc). I don't like receiving them and I think they're a waste of money and environmentally poor. I never, ever send any (so it's not like I seem discriminatory).
My mum (fyi, I'm a 40yo adult with 2 kids of own) insists on buying a card on my behalf and either having me sign it or signing it on my behalf! Recently she's done it for my brother's wedding (I gave them a generous cash gift) and my step-sisters birthday (I'd bought her a gift).
Today she tried to get me to sign one for my her husband's birthday (they've only been married 18months, so he's not my step dad - that's not me being mean, I do like the bloke). I just refused and I told her I'd message him to make clear the card 'from' me was not from me.
Would you be annoyed at this? It's not like I forget or I send certain people cards, it's an active choice I've made!
Yes it may seem petty but it's happened 3 times in 3 weeks and I'm getting pissed off.
