One of my students brought me a bag of yummy treat this morning, happily telling me, "Happy New Year!"
My student is Indian and his family celebrates the Festival of Lights holiday by handing out presents and treats to friends and family members.
The Diwali holiday received it's name because it's literal translation is "row of lamps". People light small clay lamps with oil to signify the triumph of good over evil. Firecrackers are often sent off to drive away evil spirits.
So wishing you all a Happy Diwali!
