Once there was a window salesman who sold one size of window. When windows first came out, people were amazed. Saying things like “I can see trees from INSIDE my house!” and “I had no idea my kitchen was so dirty!” Windows sales were through the roof, so to speak. But soon people got bored. It seemed like everyone had windows now. Curtain sales were pretty brisk. Anyway, the windows salesman had a great idea while eating breakfast one day. Bigger windows! And he was right. People were tearing out their old windows and putting in bigger ones just as fast as the windows factory could make them. You can see where this is going. Eventually, the windows got so big that people were living in glass houses and LOVING it. The birds not so much.
Moral: You can have too much of a good thing.
