There is a guy I have class with who I have developed a little crush on. He is a few years older than me and I don't really know much about him, but I would like to change that. The problem is, I know enough about him to know he is not in a position to go out with me at the moment. I want to let him know I am interested and, when he is available, would like to get to know him better. How can I do that without making our limited interaction incredibly awkward?
