Keys

I'm finding keys all over the place, in drawers, boxes, pockets, shelves...you get the idea. So I started putting all the keys I found around the house in just one place as I came across them somewhere. This has amounted to a *lot* of keys, most of which I have no idea which locks are for! A good deal of these came with the apartment when I bought it, but most locks in the house have been changed since then. I can't bring myself to thorw them out though, for I'm sure I'll find a corresponding lock as soon as I do....
