Even if you ask me, it will be no use..

I dislike it to be emotional and if possible, I really doesn't even want to have a moody face around everyone. I doesn't like to be the cause of everyone's sadness but then I can feel of it that what I'm doing really do cause some sadness among them. I'm sorry, I don't mean it but I doesn't know what is happening within me. Somehow, I know what I'm doing seems like to be wrong, but I believe it that with my ignorant behaviour, I can make some of your behaviour to be extinct.. or at least I hope it works.. Well, that depends on how much I worth for you in your heart then.

So confuse with all the things that is happening all this long.. Who am I..?
