20 plus years ago I had a deal similar to this. It was before everybody had a video camera in their hands and wanted to tape everything.
My wife at the time was driving down the road and a punk passed her and flipped her off. She gave me a license number and I found the car at the High School. I waited until the kid came out and ask him about it. Very matter of fact told me yeah, I did it. I offered an out, asking if she had done something stupid while driving, but he said no, I just flipped her off. At this point he could have ended it with a “tell her I’m sorry”, but no,,,,,,,,,,,, he just kept on pushing buttons.
When he had pushed enough buttons, I held him there and told somebody to get the Superintendent as we needed to talk. Superintendent showed up and was more old school than myself and told the boy none of this would have happened if he had not made an obscene gesture.
Everybody left and the Superintendent told me he was good with everything, but in the future please, don’t hold the kid by his throat.
