that the street you need to turn on isn't marked
the only dollar bill you have isn't accepted by the vending machine and there isn't a change machine
the store you go to specifically for a certain item won't have it or will be out of it
the phone will ring as you sit down to dinner
the power will go out just before the climax of the movie
you smiled at the word 'climax'
you believe the claims of a 12-hour lipstick even when you know better
