Why is he acting silly around me?

Anonymous

He's a coworker of mine and we hardly talk, maybe just here and there when we get to work together.
But in the last two weeks I have noticed that he acts sorta cute/silly around me. I'm confused, is he being mean? Or just being playfull? Or perhaps he likes me?

The things he'll do:

-One time, someone complimented on my sweater. I did not get the chance to respond to that person because he responded for me and said "oh, why thank you". (I thought that was hilarous but silly of him to do that because he has such a tough exterior look to him)

- I gave someone a smile and two thumbs up and since he was present in that moment. He turn facing me and mimic my same exact gesture.

-He had never said "bye" to me before but the other night when i was about to clock out from work he said, "see ya"

-Last but not least, I was standing with both of my arm resting on top of a desk. He came and stood beside me and the back of his hand brushed against mine.
