Hurrah! I have now cleared out the kitchen area again. The old computer we were working on on the kitchen table has been donated to the local senior center, along with a large box full of old keyboards, power supplies, and so on. So that is done!
I've sold most of our old receivers / stereo equipment on ebay. The few remaining items are listed on Amazon and ebay and are going into the spare room until they get bought.
There's just a few items left in the kitchen to move to their proper homes, and then I can actually vacuum and clean the floor! And I can do yoga again. Hurrah!
