I used to get the razor strap when I was young, believe me when I say we did not mess up to often, now I slaped my sons bum when he is bad with my hand, he once told me he was calling 911, so I told him if he did he may as well ask for an ambulance to, needless to say he didn't make that call and has not made that comment again. Now when he talks to his new Mama he is always " yes ma'm and no ma'm " and very respectful of his elders.
