What things have you randomly found?

There used to be a boy who lived across the street from me n my cousin. He was really nice to us but always thinner than most boys his age.

Well he moved away. One day I went to the house he lived in. A relatively nice two story. It was still crappy like the other houses but the exterior was decent at least. I look down in the dirt and found a key.

No idea what the key is to. But I think I still have it to this day. Perhaps it was a spare key for the front door. But sometimes I wonder, especially with all the crazy crap I read online.
