Singing at a Park

This happened back when I was 14, but even with my bad memory, I remember this years later. I honestly think that this memory will haunt me for the rest of my life. The man looked like he was some kind of ghost and wasn't out exercising or anything like that. He clearly watched me as I passed by and tried to pretend we didn't notice each other. Once past the intersection it became very clear that there was no one else around who could have seen him in such a small area.
