Lisa's having a tougher time getting around, with her leg problems aggravated by a sore back right now.  The sore back is probably due to over-doing a bit while I was gone for the last three days on a business trip, though overall Lisa did pretty well on her own.  I'm glad to be back, and of course we're grateful that Lisa had friends and neighbors to call if there had been any kind of a big problem while I was away.
