Some people because of lack of time are unable to communicate normally with friends and acquaintances. They have to settle for "fast communication". For example, when the moment of the session, I work to prepare for exams and I have no time to walk or to talk. At the Institute, I see a lot of my friends and I, thus, there is a "rapid communication". We for 5-10 minutes , asking how each other's business, quickly sharing something important for yourself and disagree. Such meetings have had their effect in day 5 pieces, which allows me to fill the need to communicate. Such communication will not make the person better or worse. On the contrary, very pleased to meet the person to whom you have sympathy and "spread the words".
