For those who helped me with the use of CTATb I want to thank all of you for your helpful comments and suggestions. I think I understand it now. Thanks again! To express my thanks, here is a little English lesson on the different expressions used to negate an action. It was Sunday, and I didn't get up. [This is neutral. The speaker assumes that it's obvious that he didn't get up because there was no work that day and no reason to get up.] It was Sunday and I wasn't about to get up. [This means that the speaker would be crazy to get up, since it was Sunday and his bed felt so cozy.] It was Sunday and there was no way (in hell) I was getting up. [This means that there was nothing in the world that was going to make the speaker get up.] It was Sunday and getting up early was out of the question. [The last thing the speaker was going to do was get up. For instance, after he heard someone knock on the door and decided not to answer it.] It was Sunday, so I opted to stay in bed/sleep in/not get up. [The speaker made a conscious choice between getting up and staying in bed.]
