For the record, shopping weighs a ton or it does when you buy a week's worth of food and have to carry it over a mile on foot. I wound up 'borrowing' an empty garbage box (about two feet by one, six inches high) to carry it the last third of the way, and hopefully will have it returned before the owner notices. For now, my arms start trembling every time I pick up my glass.
I also had the pleasure of a surprise driving lesson five minutes after I got back from walking the dogs -- surprise because I thought he was away for the week. Which he is, now. Oh, and the weather is boiling.
