Is this flirty behavior?

*Asking in a different category since I can't delete my first question

A newer co-worker was working solely with me today (just us 2 in the area for the day) and he was extremely chatty with me. He does like to talk to people and is pretty sociable, but it seemed like he may have been trying to hit on me a little.

The first time we ever worked together/met, he commented that I was quiet and kept trying to get me to talk to him/interact with me.

Today, when it was just us together, he started to be very talkative. He was doing things to make me laugh all day (telling jokes, making fun of different work situations, etc.), he was being really courteous and helped me clean up at the end of the shift, he asked me what my favorite artist is, etc. He comes into my space/stands close to me as well.

My biggest tip off for possible flirting was a comment he made. I was coming through and joked I was going to take him out (as in run him over) he laughed and was like well that's not what I had in mind for "take me out" - I was thinking "sweet a free meal".

So does it seem like he's starting to be flirty?
