"Ei nu mă vedeau!"
Translation:They did not see me!
Why you ask? I think there is some textbook that says that the English verb to see can't be used in the progressive (were seeing, am seeing) because either you see or you don't, that there is nothing gradual about it. I believe this grammar rule is not observed by people who actually speak English. Evidence for my assertion? We are both here scratching our heads....
