"I am not in the business of making private conversation public," Gandhi said.

His comment came in the backdrop of recent reports that Advani was touched by his gesture of walking up to him at the Delhi airport's VIP lounge, and that the BJP leader had told him that the two mainstream parties should treat each other as ‘political adversaries and not enemies’.

"I don't have a sense of disappointment," he said when asked how he felt about a private conversation being made public.

"I have a certain obligation. It is his (Advani) prerogative," he said.

He said he had a ‘chance meeting’ with Advani at the airport.

Asked whether he considered BJP as a political adversary, he said, "they are our political adversary and we have fundamental differences with them."
