nuts n bolts

Sometimes I find random nuts and screws and bolts and stuff on the ground when I'm outside and I always wonder where they came from.  They don't look new enough to be just a new thing someone bought and dropped accidentally.  What's going to happen to the thing it came from?  It might break, or might not even work now because one little piece fell off.  Of course, it can be replaced, like most things.  Unless you're a company that sells parts that are only compatible with that product.  You suck.
