Yes, people who are different from each other can be friends. The Right to Education (RTE) has made a provision that children of poor family in India would study in public schools. In these schools, children from well-off or rich families are also studying. It is very likely that these children with different backgrounds would sit together and may even become friends. So, while children may come from different backgrounds nothing stops them from becoming friends. They may be rich or poor and may belong to different caste, religion, creed, culture, race or colour. Diversity may even be reflected in their language, food habits, quality of dress or shoes and so on.
