My daughter was 5 or 6 at the time. When they are that age you are teaching them what not to say. "Don't call anyone dumb or stupid, those aren't nice words."
We were out and about and I decided to go to an Al-Anon meeting. The meeting had already started. It was a small meeting, about 8 people. We went in, sat down, and my daughter was quietly amusing herself with the toys I had brought in for her.
A woman was sharing, and was visibly upset. She was sobbing and she mentioned that some event had made her "feel so stupid". My daughter stopped what she was doing, looked up at me and said "Stupid! She said Stupid!" I tried to quiet her but she continued "She said stupid!". By now there were snickers coming from others in the meeting. I just gathered our things and left the room amongst the snickering and the intense, dagger throwing stare from the woman who we had interrupted.
Needless to say, I never showed my face at that meeting again.
