Mrs. L v1.0 was from India. Her sister married while I was visiting—I think she defended her doctoral dissertation a few months after her (arranged) marriage. The parents felt they needed to marry her off, but she was content being single.
I can’t speak to all cases but I would challenge the “two random people” characterization. Her parents didn’t pick for her…she met half a dozen men at least. In each case she (and the man) had the choice to continue or not. So they do have some choice. Toward the end, her parents said, “Hey, we can’t keep doing this forever,” so there was some pressure to pick.
v1.0 told me that affairs aren’t that uncommon. I found this, which seems to corroborate that.
I have a theory about it. When you live in a poor country, your family is your wealth. You might be ill but someone else is bringing in money so life goes on. In that sense, the family has an interest in whom you marry.
In fact, I recall that when v1.0’s sister agreed, a series of gifts were exchanged between them. I remember the parents of the bride-to-be were supposed to give the groom-to-be a wristwatch. I remember that they look these gift horses in the mouth. “How nice does that wristwatch need to be? We don’t want to offend them…how nice was the last gift they gave her?” In a way, I thought it was good that they check out each other’s finances, sort of.
To keep feeding the economic engine, the marriage needs to produce children. Once that has been accomplished, it’s all good.
No, they don’t love each other when they marry. If you were in such a marriage, maybe you’d make a deal with your spouse: let’s look the other way when the other cheats. Don’t be obvious—don’t be indiscreet—and I won’t make you look bad, either.
She said that they have a break during the day, like the siesta of Latin America. They like to take an extended break (wink wink) during the day.
