Embarrassed to have company over? to entertain outdoors?
Solution: Invite a crowd of women over, really cute, young women. He gives you eyesight pollution; you give him noise pollution. Make sure their "critique" of your nature loving neighbor's body flaws can be heard. The volume of the barbs can be aided with liberal application of alchohol to your guests. Let him hear you "defend" his honor as a good neighbor should with such kind remarks as, "Look, I'm sure it'll happen to ALL of us...eventually..." and "Pshaw, that's probably from whatever he was sitting on before he came outside."
