Back and forth

Have you done it yet? You should have done it. You had plenty of time to do it. You had all day Tuesday and Saturday... what did you do? why didn't you do it? you knew you had to do it, it's not that difficult is it? What you're gonna do now? I mean, you can't go back...you can't tell them you haven't done it. You should have done it... it's too late now. I just don't understand.
