That's one thing I noticed - the author doesn't say "would you like me to introduce you to X who you could talk to about Y?". He says "hey, go talk to that guy" and thinks he's being kind. He's not. What Aditya could be hearing is "you're some kind of loser, there are so many obvious things any normal person would do, and you are doing none of them. Let me list some ways in which you are a loser. For example, you could be talking to that cool guy and you don't. And now that I told you that I'm going to leave you to soak in your loser-ness while I am going to have fun with my cool friends!". It's probably not what the author meant at all. But that's what it easily could become. Aditya clearly has some trouble connecting to strange people, for one reason or another. A kind thing would be to try to help him, not to label him "closed heart" and dismiss him. Of course, nobody owes him that, but if you proudly declare it's your job... If you think telling an introvert not having a good time "why don't you have a good time! go and have good time right now!" is going to work, you clearly don't understand how introverts work.
