Why did my crush point at me at lunch while talking to a friend?

Okay, this happened awhile ago, but I kinda have a feeling that he asked his friend (I've known his friend since the first grade) what my name was.

I was eating with my friend at one of the patio tables, in front of the snack bar, and he suddenly walked up to the snack bar with the friend and looked at me. they continued talking for a few seconds, and his friend pointed at me. My friend saw some of it, and at this point I think they were talking about me, especially cuz before that, even though he sat in front of me and we were kinda like friends, he'd never really bother about my name. And a little after that he called my by my name, not my nickname, which is what he would've called me by if my friends who sat by him told him. If still confused about what that meant, though..
