Mumbai, Jan. 21 -- "It's from a book that I put together a few years ago," said author Twinkle Khanna, about the photograph she had posted on social media, on the occasion of the 18th anniversary of her marriage to Rajiv Hari Om Bhatia aka Akshay Kumar that fell last week. The post had featured a photograph of a casually-dressed Khanna and Kumar schlepping hand-in-hand down a tree-lined street, with the words, 'Why would I want a man just like me, What would I learn from him? What would he learn from me?' with the heading, 'Two Peas in a Pod died of inertia'. "It's very precious as there are only 5-6 copies printed, filled with pictures, anecdotes and all the letters that we have written to each other and to our children over the years," she said, about the exclusive personal memoir that she had created for a few private eyes only. The couple, both stratospherically successful in their own rights, but perceived as being very different individuals, (one bookish, the other brawn-ish) had defined the opposites attract syndrome and hence, Khanna's 'two peas in the pod dying of boredom' allusion. Since her anniversary, the wordsmith had created a delightfully-piquant commentary on the state of the union, with a series of "What did your husband get you for your anniversary", with the hashtag #18years. "Fortunately, he gave me 18 years of solid friendship, enough space so I could grow and somehow managed to hold my hand for a large part of the way. This is not the end. Apparently, we are just on page 120!" Twinkle had posted. Nice....
