Hi! So I have this coworker who treats me very different compare to all the other workers! He pays more attention to me and he's more playful with me. His best friend works there as well and he even said that he is more mean with me. But not in a mean way like hurting my feelins, but in a more playful way. Also, he tries to find learn more of me! Like what are my hobbies, who are my close friends, etc. He smiles at me all times, and any time we are alone he tries to pick on me. I was at the hospital one time, and he gave me his number if I needed to talk to him or if anything came up.
Is there a chance he may be interested in me ?

Ask him. Why would you speculate when you know him, work with him, and can just talk to him? Are you just curious or interested enough to find out?

I would love to ask him, but there is a thing that is stopping.me from asking him. If he doesn't, it would make things awkward. My older.brother works there as well, which is another thing that would.make things awkward.

How old is he? Picking on people to show interest is very childish. Is he a young teen? Are you?

How old are you both ? To me he seems young. And as you have noticed all the things that he does, are you interested in him ?

I have to agree, this sounds like a teenage thing, Of course if he is 16 and picking on you, that means he likes you.

If he is 40, it means he is not very mature.

And it most likely , will get awkward anyway, assuming most dating, ends, dating a co worker is almost always ending in strange
