My teenage son who is 16yrs is currently driving me nuts. Since moving into our new property in march I have stipulated that he cannot have food or glasses of drinks in his bedroom because he has new carpet in the room. My son at best can be a slob and for the most part let a lot of things slide. But this has been one issue that I have tried to establish since he was small. Now that he has a larger room with new carpet I let him have a bottle of water with the pop up top on it only in the room. He has a tendency to spill things or let things drop where they are. This simple rule has caused so much headache with him as he has consistantly insisted in taking glasses of drinks into his room. The last time I took his television off him which was the first time that I backed up my stand on the issue (much to his dislike). Nevertheless again he is taking drinks in his room. I hate getting angry over the issue but it is just that I get so frustrated with him. Basically he is a good kid who doesn't drink, smoke or take drugs and is focused on completing his education. They say alcohol is cunning, baffling and powerful, well NEWSFLASH so are teenagers. How do I get this kid to listen to me. I have tried certain strategies to get his attention and to make him listen to what I am saying and they have in the past worked but when it comes to this issue it all seems to be futile. Any feedback would be appreciated.
