It's funny...I've actually never really felt like there was pressure on couples to NOT have kids in the area where I grew up-- or maybe it's more generational. I feel like couples who have the means and circumstances to have children and DON'T are looked at with suspicion. There are quite a few couples in my area who both work full time at decent jobs and choose not to have kids and they are constantly badgered by those of the 50+ crowd with statements like:
"Oh, we wish you two would finally just start a family", or
"It's such a shame that none of you couples seem to be having kids", or
"It's so sad. When we were younger, everyone had 3 kids by your age. There were little ones running all over the hall after the meetings. Hardly anyone has kids these days."
Then you watch the looks on their faces when you reply:
"I'd love to have kids too, but given the fact that only 1 in 3 kids stay in 'The Truth' TM , I really don't want to take those chances of never getting to talk to my kids or grandkids someday. Would YOU play those odds?"
They get this depressed/forlorn/sad look of realization across their face and mutter something about "well I'm sure that wouldn't happen in your case" and quickly end the conversation.
