I was at a park today with my dogs. I saw a group of girls having a picnic on the grass and flying a drone around. 

My dog was chasing the drone so I started chatting with them.

It turns out the drone wasn't theirs, but it had been hovering over them creepily for a while.

It got within a few feet of me head on and I flipped it off.

In retrospect I regret not knocking it out of the sky. There are some strange people out there.
