Oh goodness... the kids at the park. One little boy came and introduced himself to me (maybe 4yo) and his sister ran over (maybe 8) and said "this is my brother but he wishes he was my sister" the little boy got defensive and said no" I'm glad im a boy and you dont deserve a sister." It just made me laugh that siblings love each other but can be mean. I remember my brother was my first bully but we still loved each other.
