Your fiance-to-be has a concert on that day and he's furious that you didn't consult him before you started making reservations. He breaks up with you on national TV and tells you to screw off and he hates you. You run out the TV studio and into the street, blinded by tears. The garbage truck doesn't see you in the middle of the street and spills trash all over your head. Then, as you stumble inside your house smelling of day old garbage, the neighbor's dog pees on your foot and you trip over the cordless phone and hit your head on the coffee table. The coffee spills onto an electrical light socket and it sparks a fire, which quickly catches onto the rest of your house. You run outside and watch helplessly as your house burns to the ground. Then, at the police station, you run into your "ex-fiance" and he tells you he's found someone else and asking you to marry him was the biggest mistake he ever made.
Better luck next time ;-)
