Location: Local fair/carnival
Characters: Me and Jack
Jack: "Mommy, can we go back to the rides after lunch?"
Me: "I doubt it buddy, it is Benny's nap time (and mine)"
Jack: "What does 'doubt' mean?
Me: "Doubt is when something is probably not going to happen, but you aren't quite sure." (I'm 'doubtful' that this is the complete and accurate definition, but it was relevant to the moment.)
Jack: "Well, there is NO doubt that we are going back to the rides today!"
