I love this thread!
I get this one frequently. The more I hear it, the more it bothers me.
"Your husband is going to leave his job? You're all going to move? The kids too??"
I liked the question initially because I feel incredibly fortunate to have my family's support. Nobody thought it was odd when we moved to advance my husband's career, though. Other moms are (disappointingly) the worst. They often say "shouldn't you wait until the kids graduate?"
