Actually it's not really surprising. She's a very simple girl, someone who a man can talk to without feeling the need to woo her, to gift her things etc. She comes off as an extremely chilling, relaxed, cool tom-boy-ish girl, something which must be very rare in Bollywood and the whole film industry. Ranbir himself has said that and I can understand where's he's coming from and why they're still good friends.
