I'm a habitual rearranger. You can ask Colin, and he'll tell you just how often it happens. If I could somehow manage to find a way to move the heavier things, you wouldn't even recognize my place! That being said, once I find a good spot for something, the spot that just clicks and says "this is my home!" I'm pretty good about leaving it.
Apparently the same is true for the layout of this blog. But I think I finally found one that says, "Hey! This is me, don't change!"
