Dhanesh Chandra Sharma, 88, has no hopes left after his 54-year-old son died in front of his eyes on May 1. At the time, Delhi was in the throes of a deadly second wave of Covid infections and people were scrambling to arrange hospital beds and oxygen cylinders. So when Mr Sharma's youngest son Sanjeev, a dentist with a clinic of his own, fell ill, the elderly man could not arrange for an ambulance to rush him to a hospital.
