Slipping and falling in rain. I don’t have an official statistic, but this has to occur like, 94% of the time at store entryways. Seriously, next time it rains, kick your feet up and enjoy the show because at least one person will take a tumble. I’ve done it myself, take a step, slip, suddenly you’re staring at the sky for a moment, then splat — you greet the pavement.
