My nephew, when he was about 5 announced to his class that his daddy shoots people. His daddy was a secret service agent and carried a weapon. BTW, he never shot anyone and my nephew is now 24 and married. On my youngest son's first day of first grade, one of the teachers was going by a different last name than she had been. From Mrs. Brown to Ms. something. The parents were talking about it and someone said maybe she got divorced. My oldest son piped up when I was talking to her and asked her if she got divorced. I don't think she heard it completely but I explained that he had overheard people wondering about the name change. Turned out there were 3 Mrs. Brown's in the school and they were trying to prevent confusion so two of them changed their name for the kids to call them. My boys are 35 and almost 38 now and I'm sure there are more stories, but I did learn to be careful when someone (or me) was gossiping because those are the things kids remember.
