Deja Vu

I was having a conversation with my Project Manager (PM) during a deadline when my whole project flashed before my eyes as a series of footsteps on the sands of time. I saw that there were two pairs of footprints, but during the most difficult times in the project there were only one set of footprints. I asked my PM "You said you will be with me throughout the project, but why have you deserted me during the most critical times of the project??" to which the PM answered "Son, I did not desert you, I was always with you...you see only one set of footprints because during those difficult times, I was sitting on your head!!"
