I kind of like this socially awkward guy who sits next to me in a few classes. After about two years of knowing me he hugs me goodbye... Sometimes. I know he feels uncomfortable so I am not rushing anything but he has a nervous habit of stroking and tugging his hair and face. It doesn't exactly look nice and it's a bit unnerving to watch. I really wanted to tell him how weird it looked without hurting his feelings so I told him if he hadn't anything better to do with his hands I could give him something to do and I held his hand for the next 5-6 mins in my hand. We were in a lecture. He didn't say anything but now even his ears blush when he sees me what should I do?
