don't you think people talk behind your back?

Yeah, I do. Not because I'm a paranoid or something like that, I do know that I tend to make mistakes in talking or behaving which my friends consider irritating or else. And sometimes, people misconceive others' words or behaviors, don't they? It is quite a typical matter anyway.
And actually, I don't really care.

Life is full of choices. You choose one and with it you land a step ahead. But remember, you can never step back, you can never press ctrl+Z and undo your choice. Nonetheless, every choice has its risk. A risk somebody has to endure in order to land in front of everybody.
