Judgemental people

So my kids had volleyball games on Saturday. Both their teams one.

Anyway as with everything I do I try and sit or stand away from the crowd. I did have a few outbursts but nothing to bad. A called out a few choice words and facial tics.

A new mother of the team walked down to me and looked at me. She said I should stay home and let the kids mother come to their games.

I told her I was a single dad and there mom left us.

She said well I can see why. Maybe if you can't control yourself you shouldn't enroll your children into these types of activities, or let someone else bring them.

I didn't even know what to say.

Is she right should I just stay home and come
