    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

    The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

    Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.

    I was living a life in my screen and hardly noticed what was around me. So when my friends invited me to go camping for a long weekend without the cell service, I thought this was exactly what I needed. Here's how keeping away from my phone for 48 hours changed me.

    I realized my bedtime routine was usually centered on one thing: my phone. Right before I went to sleep, I browsed through news websites and checked my emails. When I woke up in the middle of the night, I did the same thing. The problem with this was I felt anxious every night. I felt free without my phone at that weekend camp. I felt asleep listening to the sound of crickets.

    When I had my phone, I was always checking the time and thinking of future plans. My thought was: “Who's going to text me now? What will I do next?” Without my phone, I truly savored what I was doing in the moment, sitting by the river, riding a bike, or singing the old songs. There was no need to rush through any of it. I listened to what my body wanted instead of what my phone was telling me to do.

    You know that moment when you're hanging out with a group of people and no one has anything to say? The typical response: Everyone immediately pulls out their phones. So what did we do without a phone to avoid embarrassing silences? We actually talked to each other. Instead of burying our faces in our screens, we looked one another in the eye, had a moment of pure human connection and then continued talking. And you know what? People actually listened.

    So, now what? Now I'm back to the real world.
