I was in the backyard with a couple of friends and he asked if he could use my computer. I didn't think he would be playing CS:S. On top of that I had knowledge that he would be hacking on my account. I came back in to check what he's doing and he was playing on the D2 deathmatch server. It didn't seem like he was using any hacks but i'm guessing that he turned it off when I got into the room since I didn't see anything.
My brother isn't willing to take a picture with me holding a sign.
