UPDATE: We called an auction company to see if they could sell the contents of the house in an Estate sale. The man was pretty frank: "My minimum fee is $1200 and you have maybe, on a good day, $2000 worth of stuff here, maybe less. You may end up owing me money when it is all said and done."
So off to goodwill it goes, once the cousins have picked over the remainder.
Such is the worth of the precious "stuff" you cling to. Certainly not worth ruining your life over, or obsessing about.
And if you think that your crap is somehow worth more than that, think again. Unless you are a multimillionaire or something, chances are, your crap isn't worth crap.
