When you put a ladder in a wet flowerbed, and then climb it with no one there to hold it for you, the ladder might shift a little, and you just might wind up falling off it. And you might land first on your ankle, then on your wrist, and then you wind up in the ER for 3 hours.
But, if you're lucky, nothing is broken and you're only in a whole lot of pain for the rest of the weekend, hobbling around on one crutch while your arm is in a sling.
Your family, however, is free to point and laugh ;)
Not that we would... heh
