Chapter 2: Exploring Our Neighbourhood

Introduction

After school, Navya and her grandfather, Dada ji, take the bus home by the market route. On the way they see a postbox, a metro train, flyovers, a hospital and a bank. At every stop Dada ji tells Navya how things were when he was young. The chapter teaches how transport and communication have changed, what community institutions do, why we save money, and how to read directions on a map.

What's in this Chapter

The postbox and the post office – Dada ji used to write letters to his brother in another city. The postman took letters from the postbox to the post office, where they were sorted by region and sent on. Replies sometimes took weeks. Today mobile phones and emails make communication much faster, though Dada ji misses the joy of a handwritten letter.

How communication changed – Long ago people used drumbeats and carvings on rocks, then letters carried by messengers and pigeons. Later came the postal service, then the telephone, radio and television. Today we use mobile phones and computers with the internet, which connect us to anyone in seconds. The book also warns that wrong news can spread quickly, so we must check that what we share is true.

Metro trains and flyovers – The metro travels very fast, and flyovers let vehicles move above busy roads and crossings, saving time. Dada ji points out that many animals, birds and trees are gone because of these changes. Navya wonders how we can develop while keeping the environment safe. Dada ji's answer: create a balance, for example by planting trees.

The hospital – A banner says "Eye Check-up Camp". Dada ji brought Navya's grandmother here for an eye operation, and the doctors helped her see better. Doctors treat patients and prescribe medicines, and nurses and other workers help too.

Savings for the Future – At the bank, Navya sees an ATM (Automated Teller Machine), which lets people take out money any time. Banks keep money safe and help us save for the future. Earlier people waited in long queues and sent money by Money Order through the post office. Now money can be sent online by mobile phone in seconds. Before money, people used the barter system, like a farmer exchanging wheat for a shepherd's milk.

Maps and directions – At home, Navya draws her neighbourhood. She finds east from the rising sun. On a map, North is up, South is down, East is on the right and West is on the left. Landmarks like parks, shops and bus stops help us give directions.
