Murhpy's flaw

Green lights and litter bins right when you need them Cats that don't get in the way when you feed them Kettles that come to the boil while you're waiting Ponds that freeze over when you feel like skating Toast that falls butter-side-up when you drop it Onto a floor that stays clean when you mop it Clouds that don't rain on the day of your wedding Teacups that don't spill all over the bedding Keys that are always right there in your pocket Hoovers that don't pull the plug from the socket Makeup that doesn't run when you've been crying Laundry that doesn’t fall down when it’s drying Phones that don't ring when you're having a shower Trains that aren't sometimes delayed by an hour Shoes that don't pinch when you're stuck in the city Photos that make you look stunningly pretty... These things would certainly make your life fab Until you got hit by that bang-on-time cab
