On a quiet road in India's capital, some children are learning again after the government closed schools because of the COVID-19 crisis.The children, ages 4 to 14, carry their books more than 2 kilometers from their homes in a poor neighborhood near the Yamuna River.They gather at a point along the road, where they receive free math, science, English and physical education classes.A singer and her husband, a former diplomat, are the teachers in this outdoor "school.”It all began with Veena Gupta's housecleaner, Dolly Sharma. She lives in the same area as the children.She said that with schools shut, children there were running wild and wasting time."If they stayed at home doing nothing, they'd become drifters,” Sharma said.Drifter is a term that describes a person who moves from place to place with no purpose or plan.Veena and Virendra Gupta decided that they should help the young people continue learning until schools reopen.
