Conditional Phrase: Che-che Reading somebody else's notebook, I had a question about one of the sentences used... "man oo ra doost daram che oo man ra doost dashteh bashad che na." The use of che-che is for the conditional phrase for "even if...or". Are there any other uses for it? How would the meaning of that sentence change if it said " che oo man ra doost dast che na"? I know this may be grammatically incorrect but could you ever say "... ya na"? Thanks!
