Dil Mein Kuch Hone Laga...

So a good friend of mine is suffering from an issue. He feels that he's somehow immune to heartache. He's the romantic type, looking to meet someone that somehow makes his heart quiver, give him the hibbijibies, and make it such that all he does is think about that person. Up until recently this has not happened to him.
And then, he meets somebody the other day, and now he's saying he feels a pain in his chest, his heart feels heavy and all he can do is day dream! Wait a second, why would you intentionally want to bring about such a calamity upon yourself? Isn't that like the worst feeling you can have when you feel so utterly powerless and helpless, cannot concentrate on anything in particular and all day long all you do is either stare at the phone or constantly checking emails and text messages hoping and waiting?
