Okay a few seconds ago I was sitting in front of my window. I was waiting for a story I clicked on to load so I gazed out the window. When I looked back down to my tablet I heard tapping on my window like someone was trying to get my attention so I looked up but then the tapping stopped. It keeps happening! I will look down and I will hear tapping. Look up, tapping stops! Like WTF!?!?!
