I have a feeling this coach has some ‘splainin’ to do.
This is not good.
The coach shouldn't have been doing this with young children and the children should have told their parents.
The parallels to child sexual abuse are there.
The kids are doing something they know they shouldn't be doing with an adult but they don't tell their parents.
I'm not claiming the coach was sexually abusing kids but it's the same idea. Doing something you know is bad and not telling mom and dad.
