Awkward conversations 1

It is not that asking if you have kids is bad question. It's just a hurtful question for those who would dearly love to have kids but for some reason it has not happened. When you first meet a person, one of the first things they ask is 'do you have kids?'. The assumption is, when you have been married as long as we have and are at our age, the next step is to have kids. So the next question, half joking, is 'why not?'. What am I meant to say? " Oh yes we've been trying for a few years and yes we've tried IVF, and no, it didn't work for us, excuse me while I go and crumble in the corner". Of course you never say this, you just make some feeble excuse ' it will happen when it happens.'...hoping that the conversation will move on from children.
