The automatic follow-up question to "are you married?" is "do you want to have any kids?" My answer is generally "No, we're not planning to. We really have no interest in having children" or something similar to that. In the past week or so I've had this conversation with around 3 different people and they always say "Well (huff). You are just too young to make that decision." I really think that if I am old enough to have kids, I am certainly old enough to choose not to. Plus, I never say "NO. ABSOLUTELY NOT. NEVEREVER IN A MILLION YEARS!" because things change, I know that! That doesn't mean I'll ever change my mind, but it doesn't slam the door shut forever. So really, just lay off!
