When a guy playfully takes your stuff, can that be a hint that he likes you?

I like my friend and he sits right next to me in science class. We talk the entire time even when we're not supposed to. Every day he takes stuff like my pens or pencils from my pencil case so that I have to kinda wrestle with him to get it back.
