When we are at school, we have a lot of friends. We meet every day. We call each other every day. And we think that we will be always together. But time passes. We are students. We meet only at weekends and on holidays. We call each other very seldom. Then we start working, marry,acquire a home and family.  And we have no time to meet and call friends. We meet once a year on the classmates meeting. We don't know how our friends live because we are busy and have no time. I think it is bad. We must keep in touch with our friends all our life. Because without our friends we are nothing. Our life becomes defective.
