Whip a 16 year old?
I did. I got so tired of Jacob doing what he wanted to do, and me telling him, and telling him to call or to clean his room before he leaves, etc. that when he called at 7 p.m. wanting me to come pick him up (after we had discussed that he was to call during the afternoon and I would pick him up at 4:30), I picked him up. Took him straight to his room and whip his butt. Now he will have something to think about next time he is doing exactly opposite of what he is suppose to be doing.
