"the answer is three-fold..."

i have so much respect for people who know exactly how many points they're going to make before they make them. i often wonder how they do it, and each time someone says "there are 3 reasons..." or the like, i'm always waiting to hear exactly what they're going to say after to check if they lived up to their claim :). (of course, i'm talking about when the speaker hasn't rehearsed their speech before and is speaking impromptu.)

impromptu is a good word for grab, i think. one would never expect it to come up :).
