I see this guy around quite a lot and he always sits alone. I've been wanting to be friends with him for a good year or two but he isn't the best with keeping a conversation. He response with the same thing to most things "good, what about you". The "what about you" part is kinda throwing me off, I'm not sure if he wants me to leave him alone or to continue talking. I really really want to be friends with him but I don't know how to get him to open up more. I know one of his interests and I know he has siblings but nothing else really.
