The other day I was playing a computer game, in which you can only move forward. So I picked up a silver key, and about a minute later the character drops the key in the sewer. Another minute later I reached a gate with a guard in front, and the guard said, "You need a key to pass." So I restart the game to try and bypass the sewer by jumping over it, which fails. So I try over and over again, with no variation. I even tried to find a hidden key, which didn't exist. Then, as I reach the guard for the fifth time, I was on the verge of rage quitting, when I realized what I had to do. Moments later I got past the guard without the silver key, how did I do it.
