If a guy notices your habits, does it mean he likes you?

This one guy always comes up to me and says: "I know what your habit is! it's biting your lip :) you always do it!" and then the next day comes back and says "I know what your NEW habit is! it's biting your nails!" he's a goofy guy so I don't know if he just likes to point these things out for fun or if he notices them because he likes me.
