Maybe im bored or self-absorbed, is this flirting

And don’t think of this as going past anything but flirting if this is what it is:
Whenever I walk into one of the offices at work theres a guy (who I like making jokes with ) that always says: “damn you work here?”/“What’s your name do you come out here often?” Or I had walked in and said “hey guys, did you miss me?” And he goes “well I always miss you”
Could just be like “joke-flirting” but not serious flirting
