This whole thing was probably just a coincidence, but it still freaks me out. I was waiting at the bus stop around two years ago, and just start chatting with this lady who was waiting for a different bus. It was just a normal conversation but there was an odd undertone that I could just barely make out, and I couldn't shake the feeling that something was off. I don't know what it was but I know it was there. Finally my bus comes, I get on and am the only one there. All of a sudden I hear "Hey!". I glance up and there's a little girl, who says "remember me?". She reminded me strangely of the woman I was speaking with at the bus stop, but younger. You could cut the tension with a knife, and when I got off I swear she watched me as the bus left.
It was probably just a coincidence, but I'm certain that I was the only one on the bus when I got on. Honestly though it still freaks me out a little bit today.
Edit: "Little girl" probably wasn't the best phrase. She was most likely around 11/12 it's common for kids to ride the bus to or from school.
