Q. 63 I tried a smile-there was no response. I offered the customary gifts-he waved them aside. I
tried the few words I knew-and with a gesture of dignity and scorn he handed me a present, asolitary egg; white and chilled it nestled in my palm. I smiled again but even I felt that my
smiles had become mechanical. There was obviously nothing for it: I would have to put on my
little act, which in my opinion is worth a whole Platoon of Assam riffles as a safety measure. I
removed my dentures. There was a roar of interest and excitement from the crowd. I put them
back another roar after I had conducted this humiliating performance several times, there was
at least a reaction. The chief’s lips began to twitch, and finally he broke into a hearty laugh.
Pointing to his grey hair, he declared, ‘I am an old man too’ and soon he was sitting beside me
very affably.
The removing of dentures by the author was intended to show that:
(a.) he was not frightened.(b.) he was old and weak in some ways.
(c.) he knew a lot of tricks to amuse people.
(d.) he did not wish to be treated as a friend.
