He's yelling at possums

My brother is in town for a visit. Last night he went out drinking with some old school friends. Several hours later I received a phone call, to see if I was awake. Having answered the phone I did happen to be awake, and agreed to drive into the city to pick him up. This is because I am an excellent sibling. And because Zeb really loves nothing more than a midnight spin.

On the return trip my brother, with the logic of the inebriated, queried whether I really was awake and whether I had been before said phone call. After we arrived home I changed back into my pajamas and then realised that the front door had been left wide open. I chalked this up to forgetfulness, having previously lived with two guys who were incredibly lax about home security (we once had to have a house meeting listing reasons it was a top idea to at least close the front door).

When I went to lock up I discovered my brother standing in the front yard staring into the distance. I also heard some distant barking. When I asked what was going on he explained "I'm just waiting for Zeb. He's yelling at possums".
