Are u sure about that?

You know, at first I was a 100% sure about it, but now that you ask, maybe there is just a small doubt creeping in. Well, what I mean is it's probbably a bit bigger than small, but certainly well above 50% sure. However, as the time approaches to do it, the uncertainty is starting to grow and now I'm wavering a lot more. It's about 50/50 as to whether or not I do it. Oh God, I don't now, not for sure. Do I really want to do it. I did initially but there's so much doubt now crept in, that I'm vering on the cautious side and am currently 75% certain I won't do it. No, you are right, I can't do it, not now, so I think I'll leave it until nect time. OK?

I am positively sure about that because I make sure of my facts before I speak.

I am going for a smoke, and I am very sure about that.
