If toi were me, would toi post this question?

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

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

If I were you, I would not be me, and if I were me, I would not post that question. toi is the opposite of me, so toi 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 toi would do, and toi would post that question.
