It's not enough to talk to plants, you also have to listen. --David Bergman
Plants grow best when we pay attention to them. That means watering, touching them, putting them in places where they will receive good light. They need people around them to notice if they are drooping at the edges or looking particularly happy in the sunlight. The more attention a plant receives, the better it will grow.
We need to be noticed in the same way. If we notice a family member or friend is drooping, perhaps we can pay some special attention to him or her. All of us need someone to care about how we are and to truly listen to us. We can share and double someone's happiness by noticing and talking about it also. We help the people around us to grow by listening to their droopy edges as well as their bright days. People need this as much as plants need light and water.
