FACT: Any box, bag, or other recepticle, whatever it's original purpose, when placed next to a garbage can, becomes a garbage can.
Reminds me of a Bruce Lee quote I heard once:
Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water my friend.
Only my example is...shall we say...lacking in elegance.
Disclaimer: This is my very own kitchen. I'm more sorry about that than you.
