Years ago, when my daughter was very young, I saw her talking to a woman standing across the street. She must have just gotten her hair done at a neighbor's home based salon across the street. At first glance, panic struck me and I screamed for her to come in doors. I was embarrassed after I thought about it...
One time in a walmart restroom there was a little boy having trouble washing and drying his hands, so I picked him up so he could do it. Then he left.
When I came out his mother was putting him in a cart. He saw me, pointed and shouted, “There’s the mad that did it!”
Obviously I was mortified and didn’t stick around to see the results.
I won’t help a child alone like that again except in an emergency.
