This cracks me up. Does it bring back memories or what! LOL!! I started dating my hubby of 8 years when he was 17. My goodness was he a pain in the butt. He REFUSED to bath. I mean he wouldn't wash his hair, shower, brush his teeth. He smelled BAD! And I do mean bad. I finally figured out that his parents weren't the nicest of people to him. They Controled every little aspect of him. The only thing he had control over was his hygiene. So he did the opposite of what they said! LOL! Finally after alot of work I got him to start bathing. He did not want them to know. He would put LOTION in his hair so it would "look" dirty! I kid you not. Anyways, now when we talk about it we laugh. He Told me how his previous girlfriend would manipulate him to get him to shower. She would pretend like she wanted to shower with him to just get him in there. LOL! Wish I had thought of that at first!
Regardless, I would look at how much control your son has of his life or if you are controlling all of it. If you are then this is a problem that you are creating. Girls can control their weight, and boys control their hygiene. Sadly I see this all the time now. Usually a big sign of an over protective or overbearing parent. I am sure you want the best for your son but if you are putting him in the situation, maybe it is time to examine how you treat him.
