Actress Deepika Padukone, who plays a ‘chaotic’ daughter in forthcoming comedy-drama film Piku, says whenever she tries to recall her fondest memories with her father, ace shuttler Prakash Padukone, she thinks of him in a lungi.The 29-year-old, who was in the capital on Monday to promote Piku along with her co-star Irrfan Khan and director Shoojit Sircar, said the movie has been a ‘challenging’ and ‘learning’ experience for her.“My fondest moment of me with my dad… every time I think of my dad, I think of him in a lungi. When I used to misbehave and my mother used to shout at me, then he wasforced to punish me,” Deepika said.
