I Swear I live in a family of idiots

So my brother has this really nasty flu bug of some description. He's been real sick since Wednesday night. I gotta tell you, I dont want to get it. As a response to that, I basically barricaded myself in the basement, where he hadnt been, so that I wouldnt get it. I get home from church today TO FIND HIM IN THE BASEMENT! Apparently the dvd player up here wouldn't work. That's all well and good, but did everyone forget how they fixed that problem when he had his wisdom teeth out last fall? They brought down his xbox and played them on that. So now, he's been everywhere byut my room. Is it really too much to ask to not let him simply roam the house, and contaminate it all? *IDIOTS*
