Surbhi Joyti: As a kid, every year as Holi approached, I loved going to the terrace with my friends in the evenings and splashing colours on them. I never realised back then about the amount of water we were wasting, but now as a responsible citizen, I feel everybody should opt for a waterless Holi and use organic gulaal to ensure that they do not end up damaging their skin in the bargain.
