Re: General manners
Excuse my ignorance, but what is the cultural divide here?
Could it be that he's just a lazy boy and needs a kick up the bum about pulling his weight around the house? For example if you expect to stay here and not pay bills and get fed etc then wash up once in a while, or at the least sort your own laundry out! Don't be too soft on the kid, treat him as you would one of your own. He should be grateful that you've let him stay, I'd be ashamed if as a teen I'd allowed myself to do the things he's doing in your home!
