This policy seemed to be true for a lot of things. Everything is reusable. I learned this over time. Although, after an excited phone call and a new work wardrobe. When washing the plastic forks we used for dinner my mother laughed, "you don't wash plastic forks." As though this had been the rule always. Its strange, all these new rules she seemed to know all along.
