When my wife and I were first married, my dad would ask us when we were going to have kids every time he visited.

At first we would tell him we didn’t know. Then after hearing the question a few dozen times, we started saying we decided not to have any kids.

For context, I’m the youngest in my family and he already had three granddaughters from my older brother and sister. My wife is the youngest in her family and her parents had no grandchildren (her oldest brother was killed by a drunk driver, and the other brother was a dickhead and his first wife was too smart to have kids with him). I know it was absolutely torturing her parents to hear us say we weren’t having kids.

We did have kids (three), but we did it on our schedule.

You might decide to have kids someday. You might not.

In your situation, I’d make up a story to explain why there were no kids that would embarrass them into never asking again. Or…if you can pull it off…just start crying and run off.
