favour of me!

yeah, some people knows me well, but some don't.
they have to learn, what i like and i hate.
i don't force you to learn about my self, just wanna tell you guys,
that i hate to repeat what i've told to someone twice.
once i think it's very clear, alright. don't ask me till i get mad.
seems like i wanna slap you hard on your face...
