We were at my husbands work picnic and there was a bounce house and the kids decided to bring basketballs into the bounce house because there was a hoop. I noticed one little girl (age 5) kept following around my son and hitting him in the face with her basketball. About the 10th time she hit him, I said something to the little girl. I nicely asked her not to throw her ball at the other kids. Her mom walked over as I was talking to her and gave me a side-eye. I know they are kids but I do think you should be watching your kid and throwing a basketball repeatedly at my sons head is excessive. Did I overstep my boundaries?
