I cant concentrate that much to analyse his body language but I have always been thinking that it would be a way to better understand him. I can't even look into his eyes very often but we can see so much into someones eyes esspecially if that person can't hide emotions and I think it's impossible to hide emotions because I can see the sadness and I see when his smile is so real, I see it into his eyes.
Sometimes I have noticed that he is breathing faster.

One time he touched his lips and I was wondering what does it means.
