I was at a appointment. I took a walk while I was awaiting another one. I was looking at buildings and something had caught my eye.

I studied it for about 7 minutes. It seemed to be something in the sky that I have never seen before. I looked on the internet when I got home but nothing about it was sighted by anyone else. People that worked there said what were you looking at? I said I'm not really sure. It wasn't a helicopter, a glider or anything thing like that. It went far away quick. The employees came out and it had vanished completely. The only reason I say it was a UFO because I couldn't identify it. I couldn't see people just the shape. There wasn't any lights.
