I"m wondering if they know how little she'll make in her "dream job." I mean, technically you can live on a first year teacher's salary--if you don't mind giving up restaurants, vacations, new clothes, car payments and entertainment.

It's a lot easier if you have two incomes.
I"m not against a guy being a stay-at-home dad at all.My hubby is a SAHD now, due to disability. He keeps the groceries bought, the bills paid, and the laundry done. I am only able to work part-time so believe me, we have had to learn to live on less and LIKE IT. That's the hard part.
I guess the question i would put to her is "where do you stand on working after you have a baby?" I know for me the answer was easy: I"m staying home. Then I"m getting a job that is flexible enough to work around our family's schedule so the kids don't have to go to daycare. I would not have taken it well if my DH decided unilaterally that HE would stay home and I would go back to work full-time. Thankfully, that didn't happen.
As far as traveling with a mid-age child, that can be done easily if you homeschool. We did it for 12 years and loved it.DS23 graduated from our homeschool. Now that DD16 is at the local high school it's actually kinda frustrating because our lives seem to revolve around school activities(I know, I'm going to miss it when she goes off to college.) We don't get to travel nearly as much as we used to.
I don't know these people and from the sounds of it, I don't want to.They both sound immature, manipulative and petty. They probably deserve each other.
