I've got a bowl-plate, a large camping mug for my liquids, a fork and a tiny spoon that I use for everything. I'll rinse them often and wash them maybe once a week. They are my staples and my roommates don't ever go near them.
My family and I have several glasses in our cupboard, but ony in particular is different from the rest in terms of shape, size, and volume. I prefer to use this unique glass for all my daily beverages, and I'll keep it a top my bureau through-outthe day so that no one else uses it.
