Parking Lot Panic
The moment you realize you forgot where you parked your car in a full lot and you panic. Often happens at shopping malls, after concerts, or after long travel trips. This is magnified at airport economy lots where you have no friggin' idea where your car is parked in lot of thousands of cars.
I got back from the two week travel and had total Parking Lot Panic on the shuttle. I wandered the economy lot for over an hour dragging all my luggage looking for my car.
