Silly person, doesn't' he know he's not paying for himself, but for you? And that you are not paying for yourself, but for him?
Indeed your character isn't really yours, but mine. You should do things to help me.
Because your not actually helping me, just like how I'm not actually helping myself! And the person that replies won't help either of us or himself, but the next person who doesn't know what to say!
So don't worry, you are in fact helping yourself by helping me help someone else. Because I'm not actually helping them.
I'm helping you, who isn't really being helped at all because it is not you to begin with!
