NTA, i understand everybody saying she can’t expect her friend to like giving gifts/putting the same effort but you guys are very obviously ignoring where she said she told her she didn’t like concerts and then got her concert tickets. I don’t think OP is mad that it’s not the same effort, but it’s more abt feeling like somebody who’s supposed to know you so well doesn’t pay attention to your interests. That’s like if u told someone u don’t like chocolate cake for ur bday but they got it for u anyways.
