Eyes

We have two of em. On our faces, at least I hope on our faces. We are almost always taking in visual images. Watching, thinking, and computing. When someone says something we always have a thought or two about. How do we know what others think? We don't. So how do we act to make others happy? We can't easily make others happy. It makes it hard. My actions everyday could cause one person to go home in tears and another with a grin. Where do we learn how to make no one cry and everyone happy? Nowhere, at least nowhere I have been. So what do we do? What can we do?
