Can a girl that's this much smaller then me like me?

OK I am the tallest kid in my class at like 6'3. The girl I like is the shortest at like 4'11. She is also really skinny and I'm husky. I think she likes me because during the morning announcements she rests her head on my shoulder. She also kissed me on the cheek once. And she sent me a note saying I was sexy out of nowhere. I thought it must be a joke because she is so much smaller than me and all the guys in our class love her. Could she really like me? I'm huge compared to her.
