What happened here?

When I got to work today I noticed the cover to my right back light broken
on my car.

I didn’t notice it before, but that hardly means much.

I don’t think I backed into anything without noticing. It’s hard to think
that someone hit me without doing more damage. Especially up that high.
Maybe something fell on it, but I can’t think what and there is no sign of
broken plastic inside the light assembly.

Not sure what happened. But, I’m not happy about it.
We’re expecting a big snow storm tomorrow. Don’t want it to fill up with
snow.
I guess I better get it fixed.
