Partly Facetious: When spouses begin to look alike

"They say that after a while spouses begin to look alike."
"That's old wives tale and speaking of old wives The Khan..."
"Hey there is scientific research behind what I said. Psychologist Robert Zajonc analyzed photos of couples when they first got married and photos of them 25 years later and with the passage of time he noted that spouses began to look similar because they begin to mimic each other's facial expressions."
"I don't equate psychology with exact science, so there!"
"Research undertaken by the Boston University School of Public Health and the University of California concluded that people normally marry within their community and couples therefore have the same ancestry and it maybe genetics that determines...."
"But The Khan married an English woman, then....then...."
"Contracted a marriage from hell; or so, reportedly, maintained The Khan."
"And then married a woman from the Wattoo clan, right, we all know; but going back to the scientists, they confirm that we choose partners who not only look like us but are also like our opposite-sex parent."
"Right so what are you trying to say. Jemima never looked like The Khan and no one has seen his current wife so who knows what she looks like except Maneka sahib and The Khan and her children...."
"Don't be facetious; what I wanted to point out was The Khan's transition with each wife. When married to Jemima he was referred to as Brown Sahib and frequently referred to the democratic norms prevalent in Western countries. I recall as recently as the Panama papers revelation when he praised the explanation given by David Cameron, the then Prime Minister of UK, of the source of funding of his offshore account to parliament and..."
"Well he was right, Nawaz Sharif should have provided documentary proof instead of pictorial non-relevant information and I am referring to Sharif distributing a picture of his dad shaking hands with a UAE Sheikh as proof of a business relationship......."
"You get side tracked so quickly. All I wanted to say was that The Khan after his third marriage has transitioned from extolling the benefits of Western democracy to committing to install Medina ki riyasat (Medina administration) in Pakistan and..."
"Shouldn't that have entailed The Khan (or his wife) taking on the project of alleviating the plight of the people of Thar, especially the children who are dying and..."
"That's in Sindh and Sindh is controlled by the Zardaris...but anyway Medina ki riyasat evokes images of the time when the Prophet May Peace Be Upon him was amongst us and that is good no!"
"The Khan has a long way to go."
"Indeed and somehow given what is happening in the country on multiple fronts - the economy, the Punjab police, the..."
"As I said a very long way to go and drat that Sharif his Motorway is making the Khan's journey ever more complicated with time."
