empty code, or is it?

I always think. I would find myself thinking, whenever, or wherever I am. Even in a crowd of loud people, or when I'm watching something. When I'm in a thinking mood, I'd always put on my serious face. I would stare at a certain point, and just be silent. Everything else is blocked out - just me and my thought. Except for the wrinkles on my forehead that would appear every time I think, my face is totally expressionless. But when my face is serious, people would look at me and say that I'm cold, unfriendly and arrogant. So, should I stop thinking?
