When I was in kindergarten, I was really shy. A classmate asked me if there was going to be hot lunch one day, and I didn't know the answer, so I said "no." She got mad because her babysitter had already packed a lunch for her or something. Well, as it turned out, we did have hot lunch that day, and she asked me why I told her we didn't have hot lunch when we did. I think she was mad at me for that. I don't remember if I responded at all.
