Arjun says there are people who will understand Hindi but will respond in English to sound cool.
"In India, if you're smart but don't understand English no one gives importance to you. If you can't speak English then you're looked at differently... This is the biggest issue in the country. You may understand Hindi but will speak in English to sound cool," he told reporters here.
The actor was speaking at the trailer launch of "Half Girlfriend" here. The romantic drama is based on the novel of the same name written by Chetan Bhagat and also stars Shraddha Kapoor.
"People are told that if you speak in English you will sound better. So, a consciousness comes in. People are made fun of, they're not taken seriously. This has personally bothered me," he says.
