The MC reminisces about his childhood. He was always an invisible, ignored kid. His mom made him give nice gifts to all his classmates, saying that he would receive them also when it's his birthday. He went to a girl's party and gave her the best gift, and she loved it, but she didn't remember it was him. When it's his birthday party, nobody came. Only then his mom stop making him go to other kids' parties.
Anybody remembers this story? Thanks in advance.
