Pondering this....

Does anyone find it strange how many mattress warehouses/stores there are, how often do people buy mattresses and why are they're typically more than one near one another. It be an easy way to move things around inconspicuously. They are never packed with people. You think donating them gives some sort of tax write off or something? By the way how often do you change your sheets? You ever wonder who else has got cracked on your bed, will you ever actually know?
