There are innumerable cases all around us in Indian communities in which relatively ineligible (say not good looking) girls have found highly eligible boys by the weight of the other factors, often dowry, and most marriages have been stable, if not successful.And, by coincidence, R, the lady who helps me with the chores around the house recounted this story about an elderly couple in whose house she's also employed in our apartment complex.
It was the husband's birthday. He had wanted a battery-operated wrist watch as a gift. The wife gave him the battery-operated watch all right.
Minus the batteries.
She had removed the batteries before she gave the watch to her husband. The husband demanded the batteries, the wife pretended that the watch did not come with any.
So, there's an example of a stable (I assure you, neither of them has any inclination to go after the next hottie that crosses their diminishing sight), but decidedly unhappy union of two souls.
