So I had an interesting morning. My housemate woke me up asking why Finley (the dog) was outside and picked up down the street. I had no idea. My event timeline of last night goes like this:
Get home from practice at roughly 1030pm.
Find front door isn't fully closed, it happens sometimes because of the weatherproofing we did around the door.
Enter and close door.
Put my stuff down and go chat with housemate about practice, video games, etc. Dog is in his room.
Go back to my room and watch TV while eating chips and salsa.
Dog comes into my room around midnight. Pet dog until dog leaves.
Lock bedroom door so dog stops bursting in and letting the cat in.
140am someone knocks on door. Go see who it is, old white guy, decide not to open door since it is 140am and why is there an old guy knocking on the door this late.
As far as I can guess, I believe that my housemate (who owns the dog and is blaming his housemates for letting the dog out) let the dog out to go pee, and since it was raining didn't stay outside. I believe he went inside and checked on his computer, figuring that he'd wait a minute and let the dog back in. I further posit that because he was drunk or high or both, he got distracted and forgot that he let the dog out, and fell asleep. Then someone who lives upstairs saw that the side door into the house was opened, and closed it, probably while on the way to the basement.
