What would you say?

Well, after much thought, my husband came up with a response to those who say "is your wife okay with that?" when they find out we have four children seven and under (and I stay home and homeschool, and don't practice any form of birth control):

"Let me put it this way: if I wasn't okay with it, she would never have married me."

Gives me intelligence, and takes him off the list of suspected abuser.
