What is the best response to a fertile's stupid/insensitive/rude question? Last night, I went for dinner with a new group of women, who all have food allergies, like me. They were mostly older and all but me and 1 other had children. To be fair, it took more than an hour for one of them to ask me if I wanted children (btw, this woman had already managed to get into conversation that she was nearly 40 when they decided to try for children and 'of course' got pregnant 'just like that' - please accompany with a finger-snap for the full 'rub my nose in it' effect). I responded with my usual 'No' uttered with a fairly positive tone, but not meeting the questionner's eyes so it should be clear that the conversation was over. That didn't do the trick and it was followed up with 'Do you want them?'. And (I'm still kicking myself) I muttered a half-incoherent 'Maybe.. sometime' and looked uncomfortable. The other non-parent at the table tried to back me up with a comment about how nice it is to give them back when they're other people's, but I didn't handle it well.
So, in retrospect AND for future instances which I'm sure there will be, what should I have said? If I've said 'Yes', again without meeting anyone's eyes, would that have ended the conversation? Or would it just have invited more questions? I'm thinking "Fuck No!" accompanied by a wince and shudder would've been a more conclusive way to end the topic. There's always the option of being honest and the satisfaction of seeing how uncomfortable people look once I launch into my infertility story, but there's just no coming back from that, is there?
All suggestions welcome!
