My new answer for all those questions like:
"Are you guys planning to have kids?"
"Soooo... what about you two?" (when anyone else's kids are near, ever)
"Do you guys just not want kids?"
In comes me, nearly four years battle-weary but super casual:
"Ya know, it's so crazy but I was just reading somewhere how that's one of the top five questions you shouldn't ask people in 2017. Apparently it's really personal or something. Can you believe it?"
A friendly reminder that no one is entitled to your personal business, and no one gets to make you feel crappy about it.
