Facebook comment

Abhishek is delighted to see her comment on his facebook status. He promptly replies to her comment. Little conversation happens, pleasantries are exchanged, ending in Abhishek's comment to which he expects her reply. He waits in anticipation, switching to the facebook tab every few minutes. After a few hours, at 4 am, he realizes she won't reply.
"Ah, screw it! I should have known better. I mean, why do I behave this way? Why should I expect a comment from her? Okay, she responded to few of my comments, but that's common courtesy, right?" Taking a deep breath, "Alright, from now on, I won't behave like an ass and waste my time on these silly online conversations."

Next morning, he gives himself the same peptalk. He opens facebook first thing, due to habit.
He sees her comment below his comment from previous night. Few comments are exchanged, ending in Abhishek's comment to which he expects her reply. He waits in anticipation...
