Paragraph:
I vividly recall my first visit, as a boy of twelve to a big town. I had hardly been outside the confines of the village where I was born and I had met and talked to no more than a few hundred people; but those few hundred I know very well. Of course, we did sometimes meet a strange face but visitors from the outside world, whose coming always aroused great excitement, were few and far between. When I reached the town that I mentioned I was first overcome by the striking change from the slow and quiet life. I had been used to. Surely those swiftly moving vehicles must inevitably collide with each other – or with us – at any moment and those tall buildings collapse and crush us all. But I soon forgot those fears and began to notice something even more amazing – the crowd people on the pavement who were hurrying past each other without a smile. It gradually dawned on me that not only were they not interested in one another; they were strangers and apparently quiet content to remain so. It was the lack of friendliness among them which most deeply distress me.
I know that if we are to profit from the many mechanical inventions of this scientific age, it is necessary for us to live together in large communities. We are thus enabled to provide and enjoy material benefits which are rarely available in small villages – such amenities as good sanitation, cheap transport and in large social and cultural life. Yet it seems to me that the mechanical inventions demand from ordinary folks so much of time and attention that they have no time left for their fellow human beings.

Precis:
A young boy visited his native town after twelve years and he was surprised by the environmental changes like traffic movement, tall buildings and busy life of the people which baffled him. He was disappointed by friendliness behavior of the town people. He agreed that blessing of Science & Technology has enabled man to enjoy comfort and luxurious life but it has made the life so fast and busy that people have hardly any time for their fellow human beings to keep social relationship alive.
