Sinché in English means until. Until I’m ready.
Until I say so. Arrogant? Pretentious? Life is pretentious.
Could you tell me the moment when you grew up? The instant you realized you were in charge of your own destiny? Until I’m ready: I live for that moment, when I can fully show myself in my prime, as my very best self. I wait because I live in anticipation, until I say so.
