good thoughts your way snowflake! i think your response is awesome! while i understand that people are curious, they really should respect your answer of later, but not now.
the bf and i have been together since high school and on and off through college, so about 8 years, steadily for 4 of them. we get everyone asking when we are finally going to get married, even our pastor has joined in the asking. we are just not ready! so the new question is 'when are you going to have kids?' oh brother! so at least for us we can say we plan on getting married first (in the next 3 or 4 years).
but i know plenty of people who are married with no children who aren't sure they want them. people just don't understand why. my aunt and uncle flat out don't want kids, they just won't fit into their busy schedule. my cousin and his wife can't have their own and are active adults so they really don't have time to go through the adoption option (not to mention just how expensive it is!). a friend of mine who recently got married is taking heat from her entire in-law family for not being pregnant yet. she so far has just smiled and said 'we are enjoying married life for now and aren't ready for a new adventure' but as most of their friends know the real answer is 'i'm not having a baby until i decide i really like them (they like kids, but babies just confuse them both)'.
kids are great, but why can't some people accept that they are not for everyone and some people don't get married just to procreate immediately?
