Your Week Ahead: A book, published in 1973, claimed that plants grew better when exposed to classical music.

When played recordings of caterpillars munching on leaves, they respond by flooding their own leaves with toxins. So somehow that information is getting through. It's possible that your efforts to get what you want are falling on deaf ears. But don't give up. If you can find the right way of phrasing your message, you can be heard and understood.
