Title edit: Talk about creepy. So we're sitting in our living room which has a big glass slider in the back with pull blinds that opens up to the backyard(condo complex). I was at the table, fiancee was on the couch right next to the window and I got up to go sit down and I saw a little "glow" out the window. I probably wouldn't of thought much of anything until it moved so I thought, oh cool "lightning bugs" but as I got closer the light hit the ground and slowly faded out. I then look up to see someone walking away! What I saw was his cigarette glowing. I grabbed the flashlight but I couldn't see anything, I didn't want to open it in case he was a serial killer or something. This morning I checked and there are tons of ashes and butts out there so he was standing out there for a while just watching us. I feel so creeped out now.
