Concentrate

More and more people spend a lot of time on their cell phones. It seems that people rely on it all the time, including while walking, eating and even going out with friends or family. Because of this, we can't concentrate on the person we are talking to, keep eye-contact or show him respect. Maybe we should put away our cell phone when we meet other people, like at a party or gathering with family, and have a good talk with them instead.
