Dealing with a teenage son

First of all let me just set the record straight that non of my kids are teenagers yet. However recently my younger brother moved in with me and these past few days, what a ride!!!!!! I am at least twenty (20) years older, married quite early, left my family in Port-Harcourt and moved to Lagos when he was about sevenish (7) so we never really developed a deep brother/sister relationship.

So come the 16th of October am staring at this young man whose basic character composition am still trying to figure out giving me an attitude simply because I asked him to do the dishes. Lets get it straight, at my house I don't have house maids catering to my every whims, so I expect everyone to chip in and do their bit of house chores but this guy thinks that just because he wears pants, that exempts him from chores bordered within the kitchen walls. You can bet your girl made it clear to him that ain't happening so get it together dude.
