Tabooo !!!!!!!

A few days back, My friend, rather not "so close" were discussing work conditions in B`lore, his dreams and materialistic desires. He suddenly asked me, why don`t you really speak about girls, bike and mobiles ? I was very normal in my reply and returned home, for if i had been late my dinner would have at stake.
After dinner that night, when i went to bed, I just gave a thought to the poser put by him, for which i really could`nt convice even myself, it was kind of perplexing that i was not speaking abt it !! well i need time to grind it and arrive at restore point...which if inot iam starting to speak on those taboo topics ??
