I don't care

Reply, "That's lovely dear. I like to be beaten on the bottom with the Woman's Weekly".

This. Most of them defines as bi even though they might not be.

Yes, I think ‘I’m not interested in their sex lives’ is a bit reductive. It’s not just their sex life, it’s their love life. Their relationships. The people they date, and bring home, and may one day marry. It’s not just about who they’re shagging.
I’m definitely interested in the relationships my children have, why wouldn’t I be? They’re important to them so they’re important to me.

What I find strange is that you appear to care what people on mumsnet think about you not caring which maybe means you do actually care a bit.

OP your message in response was perfect.

But your post here sounded very blunt and quite dismissive.

In my opinion those posters saying they have no interest in the sex lives of their children are taking too reductive a view of this. It’s not just about sex, it’s who you date, who you hold hands with in public, who you attend events with.

Being bi can be very tricky to navigate. My daughter was bi. The relationship she had with a woman was very significant, yet she felt it was erased by others (not by us, her parents, but by friends and wider family) after they split up.

Do you mean that you don't mind rather than you don't care?

One's children, I think, are about as comfortable to discuss their sex life with their parents as they are to hear about their parents' sex life.

I see how it could be a revelation to ensure that you are not ignorant, but not an announcement for fruitful discussion until the right moment. You know your child best.

In future, as you meet and greet partners, knowing your child's status might be useful.

Yes, I agree. They might as well have texted you with a description of their 'type' for all the relevance it has to anyone but them.

I can understand them saying theyre bisexual if it came up in conversation, but to just send a random text is odd.

My above post was a reply to @SeaShellsSanctuary1

OP's post reasonably asked AIBU not to care about [her] offspring announcing they're bi. It wasn't a "need to publish their news to the population of the globe" ffs.

I don't know how one would respond to such a revelation, other than "that's nice dear." I really don't care either what my kids' sexuality is. I care about the human beings they're dating, whether they're finding love, and whether the relationship is working well for them, but the sex of the partner is pretty irrelevant to me.

If you don't care why did you feel the need to publish their news to the population of the globe.

I think it's great that you don't care. Kids these days (yep, I said it!) want everyone to center their latest issues too. The fact that it doesn't make any difference to you says to me that you take your kids at face value as whole people, and little details of their lives aren't going to make or break your relationship with them.

It wasn’t meant to be dismissive. It was meant to indicate that what they texted her was alright with her and she wasn’t going to make a big deal out of it. Some parents would and do freak out about learning their offspring are bisexual or gay. A friend of mine’s son told his parents he was gay. When a woman in her book club asked how Jack was, my friend said he’d gotten a summer job and had recently told them he was gay. The book club woman said, “Are you taking him to therapy?” My friend said, “No, why would I? He’s happy.” Just ordinary, you know?” Not dismissive, just accepting.

Well, yes, exactly.

GREAT 👍 - why, is it better than het or homo?

INTERESTING - really, you're interested in your kids' sex lives?

OH, DEAR - nah, you wouldn't.

ANY PARTICULAR REASON YOU'RE TELLING ME THIS NOW? - oh, no, mum, you're asking about the details of my sex life? Cringe!

Maybe they had a bet on how OP would react 😏

But fascists and nazis tend not to have it in specifically for left-handed people. Although, if they ran out of people to hate, I wouldn't put it past them.

Well, 10% of young people in the UK identify as bi, gay or lesbian. That's about the same as the percentage of people who are left handed.

The country is veering towards the far right. From a young person's point of view, I wouldn't be so sure it's such a non-event to announce that they're not heterosexual, sadly.

Not sure that a young person announcing they are bi even qualifies as 'coming out' in 2026 tbh.

Why is coming out even a thing?

Extremely appropriate response. Well done.

Aren't most youngs bisexual at the minute? Who cares. YANBU.

What a strange post

Surely the majority of people wouldn't care either way (as in they care about their child, but they don't care whether they date men or women).

Same. And immediately turning the conversation to eg a sushi restaurant sounds dismissive rather than accepting to me.
