I know I am very lucky that people want to buy me a present for Christmas, and I do really appreciate it, honestly, but...
By present pressure, I mean someone who will ask what you want, and not give up until you've given them an exact answer (probably including a link to a website they can buy it from). I genuinely mean it when I say I don't need anything, however I do understand that it is nice to buy things for other people.
Therefore, AIBU to think that if you want to buy a present for someone, you shouldn't put them under so much pressure by demanding to know exactly what you should buy them? It really makes me want to say that I don't want them to buy me anything at all, because the questioning and then annoyance when I can't think of anything makes me feel quite sad.
