Childless and changed.

Grandchildren are rarely as fascinating as their grandparents think.

I have quite a few very closed friends who do not have children and I find them the least judgemental about my parenting maybe it's just your friends personality? maybe she just wants to talk about other stuff? maybe you have just grown apart? If it was her choice not to have children, I doubt she regrets it

I seldom ask my friends how their children/grandchildren are. We will eventually probably get round to the subject but only when it comes up because we are visiting or doing GP duties. The only time I would ask is if I knew they had been going through a hard time or been ill. I wonder if they think I'm resentful? Or maybe I regret having children??? We have much more interesting things to talk about.

I also get fed up of listening to my friends talk about their grandchildren, even though it’s not always the main topic of conversation, someone always mentions them or boasts about them. I do have grandchildren but I’ve not seen them for four years as they live in the US and my son, now divorced from their mum, is useless at keeping in touch. It’s not upsetting for me and I’m not jealous but it’s just boring to hear what “cute” things they say or do or have to look at photos.

At my book group, there is about half an hour of talking about grandchildren before we start discussing the book which can be tedious. I don’t think my friends realise how much they talk about their grandchildren! There is one person in particular who talks about little else yet I’m sure if asked, they would not think that they were like this.

So I can empathise with your friend but I don’t think I show my feelings, I just sit quietly as I have nothing much to add to the conversation and try to change the subject after a while.

Other peoples grandchildren are often a boring subject even when you have your own.

If I am completely honest although I have children and grandchildren I have very little interest in other people's grandchildren. I would always ask friend's how their children are but I don't ask after grandchildren. There's always lots more interesting to talk about. Rather than being resentful, could it be that she's just not interested?

Lots of GP dont have access to GC for a variety of reasons.
Some of them probably dont want to talk of others GC. very much, if at all.
Does it matter really?

We all make choices in life and hers was what it was, I can understand after a lifetime of even small talk about children grandchildren that she has probably zoned out, after all that’s a big part of yours (our) lives and not hers even if you don’t talk about them much you all have a common bond that she doesn’t have
Ask her if you want an answer to your question, no one else will ever know and can’t possibly judge
As long as she’s a true and supportive friend it doesn’t matter what’s inside her own head does it ?

As I don’t know her I have no idea how your friend feels. How does her being ‘resentful’ manifest?
