For Preity Zinta 'Independence Day' is a big occasion. And the word 'India' holds a special place in her heart. She thinks past is the greatest teacher, we should learn from it and co-exist together happily. "So many people from different backgrounds, different parts of the country, came together and sacrificed so much so that we could be independent. This makes Independence Day special for me.
