Running out of shampoo

This month I'm going to run out of shampoo.  I shower every day and I probably need a good tablespoon of shampoo to wash my thinning hair.  This month I'll run out of shampoo.  Why is that such a big deal?  I haven't bought any shampoo in at least 4 decades.  My wife always bought the shampoo, along with a lot of other things she managed.  My wife died 11 September 2012.  She was a bit of a hoarder.  She would buy stuff on sale.  She didn't seem to keep track of what we had on hand.  It was on sale so she would buy it.  After he death I began a purge.  Some things I doesn't know what I should do with them.  I have books and books of Postal Commemorative stamps that are only worth the value of the stamps which means I have to clip open and put tons of stamps on stuff. But in addition to lots of shampoo I still have at least 8 packs of forever stamps, and don't get me started on two dollar bills.   Anyway I'm running out of shampoo.  You can estimate anyway you want, but understand that I had a lot of shampoo stored in the bath closet.  It is another milestone.  A sad one, but nonetheless another milestone.  As each day passes I lose another physical contact with my wife.  Our dog has cancer.  He probably won't make it another 12 months, and he is only 9 years old, but that is another chapter for another night.
