On my 19th birthday i had a party with close friends and after it ended, i opened my presents and letter. I read my bestfriend's letter and it was mostly about how i hurt her. On my birthday card. I was so flabbergasted. I thought birthday letters were supposed to be about celebrating and showing gratitude and love to the birthday person. Well yeah this is one of the many things she has done that has hurt me over the years of our friendships. And the things she said i did were i ate lunch without her when she was hungry (which she didnt tell me so idk how i was supposed to know) And the other is i didn't defend her properly to our other friend when she said something bad about her(they had a fallout) (p.s i did defend but she wasn't satisfied ig). When i confronted to her about it sometime later, she said that she thought it would be okay because SHE would be okay and grateful if someone pointed out her mistakes on her birthday letter.
