I witnessed a dad full on beating on his son in public. I was stunned and froze in place.

I don't know what happened to lead to that point but the kid looked around maybe 8? I grew up mainly in the 70s so I'm no stranger to getting popped but I was takenaback. He was just yelling at and smacking the heck out of the poor kid. I was rooted to the spot too stunned to move. I regret not saying or doing something. We were in a grocery store right outside the entrance.i wasn't the only witness but I sincerely hope that kid is alright. I really kick myself for just being a stupid bystander.I'm worthless when it comes to confrontation and I feel I'm too laidback most of the time. Too complacent.
