Many many many years ago, my mother (as a new bride) stored her fancy wedding presents in her parents' attic while she followed my father (a military officer) to an overseas posting. Thirty-some years later, when my grandmother died, my mother retrieved her unused wedding presents from the attic and sold them to an antique dealer. Moral: there are a great many things you probably will not ever want to see again after they've been in storage for several years. Sell 'em now.
I totally agree. I love getting rid of stuff (either selling or donating it). If the original poster would like, I could draw up a list of everything they should just give away, and I'll do it free of charge ;-)
