Actually, that was a rather silly explanation of the problem. The problem lies not in thinking of a glib opening line. Rather, it's the inadequacy of verbal communication. When you first meet someone, your story has to cohere. It's all a lie.
Some people are good at the lie.
Some people get so scared by the lie that they are painfully afraid to speak and hate themselves for it. Then, to think that, even if one could transcend the problem of verbal communication, even if a light could splay one's nerves and truest thoughts onto a screen, he would meet revulsion. The thought quells the pitch of action. Looking back, one either thinks he waited in vain for his hopes to materialize or thinks he came off jolly well and has no regrets. The former suffers melancholy, the latter almost always accepts delusion.
