Does the guy at work like me?

There's this guy at work. I'm 37 & he's 45.

He's a manager but not my manager.

We get along quite well. We talk when we bump into eachother & he has to walk past me to get to his office & always says good morning & goodnight.

So he finished work a bit early today & it was weird.

He always waves to me but this time he waved, stood there for what seemed like a while & just smiled for the longest time at me.

I don't know if he's just being polite but just got this weird vibe how he did it.

Am I over thinking it.
