A Kerala teen who was seen in a viral video riding a horse in school uniform has revealed why she decided to take that form of transport. "I do not go daily on horses. Only on some special days, or when I get bored or on some exam days also, I ride on a horse to school. If you ask me what was special on that day that was the last day of my Class 10 board exam," Krishna, a resident of Kerala's Thrissur district, told news agency ANI.
