I was doing pretty well in a local pub game a good number of years ago. I had KK, and lost the hand, I still had some chips tho, enough to mount a comeback, I got dealt AA next hand, I shoved and got called by the same player and lost again.
I don't think I will ever forget this situation!
I am now over it, many years later, and its more of a comedy story than the crushing defeat it was at the time!
