It is easy to impress Sonam, says Dhanush

South actor-singer Dhanush, who is paired opposite Sonam Kapoor in 'Raanjhnaa', says the actress never made him feel uncomfortable and was rather easy to impress.

"She is a sweetheart. She made sure I did not feel discomfort. She was quite patient when I was getting my Hindi wrong. She helped me a lot. It is easy to laugh, as I would have lost my confidence," Dhanush told reporters at the promotional event of 'Raanjhnaa'.
