Why?

I have the most difficult roommate in Silicon Valley.  He continually messes with my stuff, much to my dismay.  I just went to turn my, MY stereo on.  He had unplugged it.  Sometime between last week and today, he unplugged it.  To save power, I assume.  Every time that happens I have to re-program the damned thing and it annoys the sh*t out of me.  He's re-programmed my coffee pot before too.  And he's unplugged my stereo before.  Despite my repeatedly asking him to STOP TOUCHING MY STUFF, he does it just to be a prick, I swear.

I think I should unplug the stove.  And the microwave.  And the garage door opener.  He has no TV any longer or I'd unplug it too.  

WTF?
