You were four so this was entirely your father’s fault, it’s not yours to own and never has been. I’m also against people making people apologize for things. Forcing an apology doesn’t make a person sorry, and if they are not sorry you’re forcing them to lie when they normally get into trouble for lying. I don’t know how she could have been a teacher that long and not recognized that you didn’t come up with that on your own. I’m sorry it went down like that. Please know it actually was not your fault. Your father knew better.
