That's the trouble with buying someone else's used stuff...Like Forrest Gumps Mama used to say: Life is like a box of chocolates, you never know what you're gonna get. Sometimes you can look at the outside, and have a good idea what's inside, but you never know for sure until you open it up.
My Mama always said Life is like a roll of toilet paper, the closer you get to the end, the faster it goes.
