What’s wrong?

These days I doesn’t smile as much as before. I don’t know why. I can’t remember what make me unhappy. This situation seems to begin since the second interview of UPA, but I don’t think it’s the reason. Maybe I read too much philosophical books these days and think too much. It’s not surprice that I lose in mind, but that I can’t cheer up when I see others. Is the inside of me and the outside begin to inosculate? I dont’ know. But I may have to change this situation because being friendly is a way to live in real life.
