About 6 years ago my family lived in an apartment. My mother had to go to late night school because she dropped out of high school, and she'd come home at about midnight. So, one night she comes home and she hears the laughter of children. She just thinks I left my TV on, and she comes into my room to turn it off, but it wasn't on. She thinks the TV in her room might be on, so she goes in there to turn it off, but that one wasn't off either.
When she told me about it, I asked her how loud the laughter was, and she said it sounded almost like it was right around her. Awkward thing about the story is, is that we went back to visit some people back in those apartments after we moved. I decided to look through my window from the old apartment, considering no one lived there. When I looked through it, I could have swore I saw a little girl. I took off and just coaxed myself into thinking it was a glare in the window.
