Could also be a pack rat. They love to hoard stuff! Not to freak you out or something.
As far as coming off a horse gracefully... Nope! I usually manage to come off in the most awkward ways. I could give anyone in my family laughing fits! But hey, when I don't fall off, I can ride an Arabian/QH bareback at a full out gallop (riding the spooks, and stops) for a 1/4 mile with out falling off (he finally stopped). I can ride a few crowhops bareback, lots of big spooks with a saddle, and my proudest accomplishment, I can ride a trot bareback with out losing my balance.
This is all when I'm in practice mind you, it's going to be a lot of fun when I get back into serious riding in the spring.
