It's probably bats. When I see them while smoking a cig, I run in the garage. About a year ago, I was pushing a friends car in my garage, and a bat flew down, jumped on my neck and started bighting me. I slapped that bitch off and was bleeding from the neck. My friends were like WTF! I finished pushing the car in, but later I was wondering if it had rabies. I never did get rabies from that so thats good. I did not even tell my parents. You know they would be like"STFU! and STOP drinking!". The bat didnt fuck me up but still, now when I see them flying around as the sun sets, I stay at the edge of the garage when smoking a cig.
