When was the last time your walked away from a discussion, only to think of The Perfect Comeback hours later? Recreate the scene for us, and use your winning line.
I can't recreate the scene because this sad scene has happened so many times that they all blend together. I could however give you a bare bones scenario; I am engaged in a conversation with someone, usually not a friend or at least not a close friend, I qualify the person because why the zing in the first place, the zing comes and everyone laughs including myself because it may be a teasing zing so I join in the laughter, but I laugh on the outside while feeling silly and uncomfortable on the inside. I disengage from the conversation as gracefully as possible under the circumstances and replay the conversation a few times throughout the next few hours when later on right before bed, BOOM, it hits me like a ton of bricks, the perfect comeback redeeming my comment for all to hear. Alas it is now six hours too late and I am not calling anyone from the group to tell it over the phone. One more missed opportunity.
