(From left) Vineet, Dhiraj, Kuldip, Sharad and Rohit.

Note that Vineet's hand is moving towards Sharad, and Sharad is trying to hide something. Sharad is actually trying to hide a new Parker pen, which I got for Vineet from Thailand. But Sharad liked the pen so much (and due to its unavailability in Indian market) he took it. That's why Vineet is trying to grab hold of the pen right before/during the picture was taken at Dhiraj's residence during his birthday party.
