Today I got home and found 3 people in my backyard staring at the roof of my house, because there was a dog on the roof. I live in an old house that is separated into an upstairs and downstairs apartment, and this dog belonged to the man who lives upstairs from me, who I don't know very well at all because he's very secretive.

Anyways, what was weird about this situation is that all the windows by the roof were closed, so no one could figure out how the dog got out there. Finally my boyfriend got a ladder and carried him down, and we called our landlord who opened up the man's apartment and we brought him back in.

Anyways, his apartment was really dirty and there was empty 40s everywhere, and barely any furniture. I know this man loves his dog because I hear him singing to him all the time, but do you think he put the dog out there on purpose?? I don't know what to do. I left him a bag of dog food, a Bible and a note saying if he needs help I'm here for him with my phone number.
So what should I do? Do you think this was intentional?
