Back in the days of the wherehouse, things used to go missing all the time. It was annoying, but I didn't take it as too much of a bad thing, lots of people came through, it was inevitable.
When something goes missing now, I usually blame myself, but I know I didn't misplace my DVDs...so when I went to put away the new Underdog DVD collection I bought, and find a half-dozen holes in what used to be a solid wall of DVDs, it kind of bugs me. It's not like my home is still a flophouse with whoknowswho coming and going. Someone I know and trust decided to borrow some DVDs. I know I loaned a DVD to someone, though I can't remember who or what, but I also remember it was only 1 DVD.
Pisses me off.
Of course, even more annoying, is having to admit I can't remember what's missing. I know for certain that A Fish Called Wanda and Labyrinth, but I can't for the life of me figure out what else is gone. yet. I'm sure it'll come to me eventually.
