Yes, parents arrange marriages for their children with children of their friends. I think parents do quite a bit of networking for years keeping up relationships with people they know with their own childrens' future mates in mind. My daughter married into a family that is originally from Pakistan. Those parents are still arranging for marriages for some of their kids (obviously NOT for my son-in-law, though).
What is really arresting to me is the lack of women out in public in Pakistan and much more so in Afghanistan. I know women have to stay home in Afghanistan unless a male relative takes them out, but it sure makes the streets look strange with only men there.
Yes, parents arrange marriages for their children with children of their friends. Can you imagine how embarrassing it must be for a prospective groom to tell his folks, "Remember, Mom & Dad, I want BIG hooters."
