I was down visiting in Pittsburgh last weekend. I spent the weekend pestering my great-aunt - who's terribly shaky on her pins & keeps wobbling around without her cane saying that she's fine so long as she can balance herself on the walls or furniture in her house - to always carry her cane around & to be more careful of falls.
Karma took notice of this, and as I was packing up my stuff and walking out of her guest room with arms full of a bulky overnight bag, my toe caught on a stool she keeps in her hallway. I took a full-on face-fault header into the floor, right in front of her. Luckily I didn't bring her down with me, so no harm no foul, but boy was that embarrassing. Much to her credit, she didn't burst out laughing like I would have if I were in her shoes.
Hopefully I've used up all the bad-fall luck in that house for the next couple weeks.
