I think Mimi was just being helpful.

I am often quite helpful in that way. My husband would never say anything to anyone about anything that wasn't his obvious business...but alas, I am a mother, and it is supremely difficult to hold my tongue when there is mothering to do.

I think helpfulness is an admirable trait. We don't know if the guy who put on the helmet fell in the next block or what. He might be on his favorite board posting about how this lady yelled at him about his helmet and he put it on and it SAVED HIS LIFE when he was hit by a bus!!

So, you never know. I say err on the side of helpfulness.
