If 你 were me, would 你 post this question?

no..i'd better go and sleep..or eat a pun cake

Well, I'd post it. Because I'd be 你 and not me, and 你 are posting this question.

If I were you, I would not be me, and if I were me, I would not post that question. 你 is the opposite of me, so 你 would do the opposite of what I would do, so if I were you, I'd post that question. Not to mention that if I were you, I'd do exactly what 你 would do, and 你 would post that question.
