Dynamite

"You ready to tell me what we're carrying?" "Why is it so important for you to know?" "Well first place, if it was nitroglycerin, then I would take another route. If it was whiskey I'd stop for a drink any time. Why is it you don't want to tell me?" "Alright, if you must know, it's dynamite." "Dynamite! Why in blazes didn't you tell me that when we started?" "If you had known would you have agreed to carry it?" "Probably not."
