Questions: Flirting

So, I have a guy friend, who I'll call Cameron. Cameron is a really quiet, but very very very sweet guy who has a cute sense of humor. We often go back and forth roasting each other or joking around.

Today, I told him that I'd help him with this large stack of clipboards he was carrying. I grabbed the container holding them, but forgot my backpack in the classroom. Cameron tried taking the handle from my hand, but I told him "No, I got it. Just gimme a second."

So I walk quickly back into the classroom and set the container on a nearby desk and sling my backpack on. I turn to see that Cameron had snuck towards the container and grabbed it. I playfully yelled, "Cameron!"

He laughed and darted out the door, with me racing after him. I caught up to him and slipped my hand on the handle next to his and he eventually let go. As we entered our destination classroom, I set them aside and he just smiled at me.

We're seniors in high schools, and I'm usually not that immature, but it was funny. Is that an immature way of flirting though? Could he like me?
