Mumbai, June 26 (IANS): She has never shied away from picking roles that are bold -- whether it's "Dev.D" or "Margarita, with a Straw" -- yet Kalki Koechlin says she was a shy person back in school -- and used to hide the weakness behind a sense of humour.

“I was a shy person in school until I reached the age of 13 and I realised that I had a sense of humour... so I was the class clown. I kind of hid my shyness behind my humour,” Kalki told IANS over phone.

She spoke to IANS on the sidelines of an interactive session she had on Thursday with students of consumer products company Procter & Gamble (P&G) Shiksha Schools here.

Talking of the importance of education, the critically acclaimed actress said: "Education is the most important thing for our country to grow. I have had the privilege to get good education. I went to an international school in Ooty. It was a place where people of different religions came together.

"We used to have a lot of sports, extra-curricular activities, creative arts and stuff.”

The actress, of half French and half Indian descent, believes that education is not just important in the academic sense, but also in terms of social education.

Launched in 2004, P&G India's flagship CSR programme P&G Shiksha has grown immensely with the help of strong support from the Bollywood fraternity including Rani Mukerji, John Abraham, Sushmita Sen, Kareena Kapoor Khan and Saif Ali Khan.
