Sorry Lillie - that's not what I meant and I realise, having re read my post, that it comes across that way.
Perhaps I've had a few bad experiences recently with people who have chatted about GCs, then turned to me and asked if I have any. When I say no, the conversation goes on and I express my view, whereupon I have received some unwanted opinions regarding how I feel.
I always ask after my friends' children and GCs, and am genuinely interested as I know they are important to them, but could we then move on to something of mutual interest? After all, I don't talk too much about singing, embroidery and trains (yes, trains) which are all very important to me, as I appreciate that you do not share my fascination/ interest in these topics.
I'm beginning to understand how couples might feel when people ask them when they're going to start a family, and they say they have chosen to be childless.
