I would like to know why the next passage is a joke.
At the company water cooler, I bragged about my children's world travels: one son was teaching in Bolivia, another was working in southern Italy, and my daughter was completing a yearlong research project in India. One co-worker's quip, however, stopped me short. "What is it about you," he asked, "that makes your kids want to get so far away?"
For the person telling the story, having children in such far-flung places was a source of pride. For the other person, perhaps having your children close and able to visit often would be a source of pride. So he is joking with the first person saying that rather than being proud to have them so far away, he should ask himself what he did to offend his children so they moved so far away from him.
I don't find it very funny.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
