He had a raw sense of humour and wrote candidly. In his own words, "My first short story was published by a magazine in Canada and thereafter, there was no going back and whatever nonsense I wrote, was published".
He candidly admitted that he was a lecher who treated women of all ages as objects of lust. So, the lecher is dead, Long live the lecher. Once an irate Canadian Khalistani wrote him a very abusive letter in Gurmukhi with the address in English which read: "To bastard Khushwant Singh, India" and it did reach him prompting him to remark that envelope with full addresses written on them do not reach their destination but this nonsensical address reached as if he was the only bastard in India.
He wrote jokes on Sikhs called Santa Banta jokes. When SGPC threatened to take action against him, he simply wrote back to them, "Go to hell". He was full of humour and had no fear for his life. My salute to him.
