Am I being paranoid?

I was paying much attention to it much, but a couple days ago a grey I think, 2011 Toyota Highland Hybrid Limited vehicle parked in front of my house. I think it was gone later this afternoon. Later though, someone from the neighborhood reported to the police that they same someone suspicious this morning. I didn't see anyone suspicious. I have read, if someone wants to break into a home, that's what the culprit would do. They stake out the house their targeting and then later on break in.

I'm not sure if I'm just being Paranoid or over worried.
