I see him on Steam 90% of the time. This means that he's sitting on his ass in front of his computer 90% of the time.
If he's one of those people that use it during school just to find someone he deserves to get slapped. If he uses it call friends and get together, he might as well do it from home since he's there 90% of the time.
If he uses it to let his parents know where he is or something, he's home 90% of the time, I don't see why he couldn't let them know where he's headed on the way out.
I don't see how my post was dumb.
