history: I thought my kid was doing great in school. Then I found out he failed one of his classes. He really upset me by not telling me he was having trouble. I thought my son was doing good in school. When I got his report card I found out he failed his math class. I wish he had told me he was in trouble.
current: It's hard for kids to do that. Maybe he was just bored?
next: He was ashamed but I told him I was only upset he didn't tell me. I know how hard it is to admit failure.
