What do you just have to keep ?

T-shirts... I still have my Infantry basic training t-shirt from 1984. It's so worn you can see through it like gauze. But there's a stack of them in the closet that I guess my heirs will have to toss in the dumpster.
T shirts, which we all know are hard to get rid of, are a constant challenge as to where to put them and still keep them around.
