That I replied to a literal aspect does not mean I failed to comprehend the spirit behind the common reddit jest about simultaneous up and down votes - and given the triviality the word lie isn't an accusation to be offended at. Perhaps I could have gone with "Lies! :P" to make the non-serious unmistakable.

Following along within the make believe reality of a jest while the actual topic is in the background is play and "I didn't really so it doesn't matter" is dropping the ball - in the counterfactual jest reality it does matter. It is good form to let others run with what you started and forcing the original frame is what makes things serious.
