Why?

Why? Why do I bother to keep living? I look out at the world and see people laughing, emjoying being around each other... And I just sit back and observe while I knit... When anyone notices that my mask has slipped, they start asking questions when all I want is to be left alone. But do they care? No. Do I speak up? Nope. Too much of a damn coward like that.
Sometimes, I think the world would be better off without me around. It's not like anyone would notice that one more stupid fatass is gone, anyway...
