My birthday was coming up and I asked 2 of my friends that I've been hanging out constantly with, if they wanted to hang out at the park or something of the sort. I always hated birthday parties because of my social anxiety and awkwardness. On the day, I show up and meet with one of the friends that i asked to come. I bought us food, we sat down and ate, then we went off to the other friends house. On the way, we meet up with another one of my friends. Turns out, they created a groupchat without my knowledge inviting friends who im not that close with and some people i dont even know. There was about 10 other people who were meant to come but only one extra person showed up. He left immediately after. The two of the original friends that I invited and me hung out for a while before we got home. They had promised me a gift, they wouldn't tell me anything about it, I waited weeks and nothing came. I asked them and they just said they aren't giving it to me. I got pretty mad because I was waiting for so long and nothing ever came. They both called me an asshole for being so greedy, they said that the birthday party was already my birthday gift and one of them said that I can also be invited to his birthday as a gift.
