A couple years ago I was out with the wife, some kid came up and put his arm around her and started pawing her.
I don't think he meant real harm, but he did cross the line.
I just one hand shoved him in the chest without even getting up from my stool.
He went skittering across the floor.
I said "don't make me stand up"
He did nothing, just kind of slinked away off to the corner
Minimum force option, legal liability in mind, I didn't want to deal with the cops.
