Thankfully, I wasn't hit too hard and don't have any major battle wounds, just a bruised leg. But my bedside table and bed were not so lucky. The table is gouged and the corner of the bookcases punched a hole straight through the foot board of my wonderful sleigh bed. It scared the living daylights out of me, of course, and I was super worried that my books had been messed up. Luke picked it all up while I laid on the bed and moaned and groaned. The good news is that all the books are ok. No need to panic. I have some nasty bruises and my bed is going to need to be replaced, but at least the corner went through the wood and not through my leg.
Lesson learned, Reader Friends: always, always, always anchor your bookcases to the wall. And, of course, once I get the bookcases rebuilt and restocked I'll be posting pictures.
