Might need to take a mulligan

That time you get off your apartment building elevator into the parking garage, and realize you never noticed that the walls of the garage were painted red. Then you walk to your parking space, and although your car is red and the car in the space is red, it is not your car. At first you think you are having a mini stroke, but then realize you got off one floor too soon. YOUR floor is painted green, and YOUR car is in YOUR spot. You then realize it's going to be a very long day.
