Bill, your bit about "I think" reminds me of a phrase my old sales manager came up with when asking us for our sales projections. We'd go down our lists of clients one by one, tell him how much we thought we'd be able to sell them in radio advertising and he'd get on us about just how sure we were of each claim. He'd say, "Is that for sure?" One of us would, "Yeah, maybe?!" He'd say, "Okay, that's a Possible-for-Sure-Maybe!"
