Hmm. Sometimes we do. Or just say, "Maybe," when we KNOW what we want (or have come to a consensus, at least.) Generally we're somehow torn on the issue, though - we want to say 'Yes' or 'No' because we think that we'll be taken a certain way for saying it, and that's the way we want to be taken, but the actual meaning of what we're saying is somehow incomplete or doesn't fit our actual desires.

Is that something like what's going on with you? (Assuming what I just said made any sense at all? ^^; )
