The worst are Mother's and Father's Day cards, I think. Some will go on about very specific things, too, like, "I loved that you took me fishing and we'd kick soccer balls in the backyard and you took me to that art museum field trip." Like things that wouldn't apply to most experiences. I'm picky about buying cards and will only buy ones that seem to apply to my own experiences and sentiments.

Shopping for cards for my parents became much more difficult after spending a bit of time in therapy, too...Like, "Not buying that 'you're not just my mom, you're my friend' card anymore, because you really tried to push yourself into my life and push your values on me and make me into an extrovert when I'm an introvert and seemed jealous of some friends I was close to, so yeah...."
