Neversaynever  +  379920 Fri, 15 Jun 07 02:19 PM Hello , My sentence is: I shouldn't have done that. I want to make it a question, but I cannot. I searched google to find a question sentence includes that (I tried many alternatives ), but couldn't find anything. I started to think that maybe we cannot form a question sentence from that, it seemed a bit weird too ? Hope, I am clear. (And this situation is also valid for "must have done" or "musn't have done") Thanks for helping me!

Or do you want to know how to form questions and negative sentences with must and mustn't?

"I shouldn't have done that." = You have done something that was not correct or not allowed. "Shouldn't I have done that?" = (1) You have not done something, and now you want to know whether it would have been better if you had. "Shouldn't I have done that?" = (2) You have done something, and now you want to know if what you did was wrong. Yankee Negatives

	Grammar Geek  +  379933 Fri, 15 Jun 07 02:51 PM I think I understand. You are telling someone what steps you took to solve a problem. You say: First I did A. Then I did B. Then I did C. At that point, the person's eyebrows shoot up and they look horrified. Their reaction says that C was not the right thing to do although you thought it was right at the time you did it. "Shouldn't I have done that?" would be fine. Grammar Geek Joined on Tue, Jan 10 2006 Veteran Member 19,683 Barbara, who answers in American English.

	Neversaynever  +  379936 Fri, 15 Jun 07 02:53 PM Thank you Yankee! And thanks GG for clarification! I understand now. Phew.. this question was on my mind for -maybe- months, I am happy that it is resolved Neversaynever

A negative question would be unusual here, but if someone were to use a negative question, this would be possible: Mustn't John / Must John not have done that? = Don't you think it's extremely probable that John did that?
