He gets a great deal of satisfaction out of making our yard look beautiful, and it does look beautiful. It really relaxes him and it gives both he and I relief from stress just looking at the precisely sculpted edging, symmetrical patio and walkways, and (mostly) weed-free beds. I especially love the view from the upstairs porch - so serene!
And who could complain about loving yard work? He could get his thrill from worse things, after all!
