Here’s what Shahid said:

The antisocial me
I am inherently very shy. Even socially, my first nature is to keep to myself. But now when I go to parties, I have learnt to become more talkative as I find that people used to assume I’m arrogant and have an attitude. I realised that it’s important, now that I am an actor, for people to feel comfortable around me. So I make that effort to talk to people.
