He's playing with me.
I just watched him walk into the house 4 times without once seeing him come out in a span of 3 hours. He knows I'm watching he's deliberately showing me that he can come and go as he pleases.
Smug bastard. I know there's two other possible exits. The garage and the fire escape. He could be using either. Without the birds I can't watch more than one.
He also must have something planned. He wouldn't be secretive about where he was going if it wasn't important.
This is infuriating. I'm gonna see if I can ask one of the proxies to ask their master if he can assign two more people to this stakeout.
