Why have adult women becomes girls again?

Probably because it makes them feel younger.

Maybe the term is patronizing to you but I'm happy for anyone older to call me a girl, it makes me feel young. I wouldn't refer to myself as one except in the context of 'girlfriend' but I'm a lot older then the age you specified. Teens and early twenties are still girls, really, or young women. 'Girls' and 'boys' doesn't need to indicate primary school age, at least not anymore. It's the twenty first century now, everything that was insulting now isn't and everything that hasn't been in fashion since the 1960s now is. Times change.

It's pretty obvious by tone when someone is being patronizing, it doesn't matter what words they use-nowadays curse words and 'insults' are used affectionately as well as to upset, this is because it depends on the tone. Some may find one thing patronizing but another doesn't, and vice versa.

Well, it always used to be considered quite normal for women to be called girls into their twenties. I don'tknow why it has become normal again after being disapproved of. I imagine that perhaps political correctness is becoming less heavy again, which is an encouraging sign.

When a young woman was called a 'girl' in past times, it did not mean she was a child, it meant she was a young woman. As in the song "I enjoy being a girl' for instance, the woman who sings that song is not identifying herself as a child, the pleasures of being female that she describes in the song are those of young women, not children.

I was calling myself a girl until I was 32, and I was in my 20s in the 80s/90s, it's nothing new. I think I did it because everyone else did, and young men didn't call themselves men, they called themselves guys. I don't know any teens or twenty somethings that call themselves women.

Most women refer to themselves as "girls" no matter what the age. I was at my church's Ladies Group this morning with several grey-haired old ladies, and the leader (my mom) said, "Well, girls, let's get started!" She and her friends refer to themselves as girls all the time.

It doesn't seem surprising to me. From the very moment they get their first wrinkles women begin to want those around them to regard them as younger than they actually are. Seriously, most women after 20-something find it flattering when people assume they're younger than they are.

Some of them also refer to their group of female friends as their "girlies". Now that's what seems weird to me.

I know I'm a "woman" rather than a "girl" but I won't feel like a woman til after I have a child... and a well-established career would help. I wish there was another word, I often use "lady" but it doesn't fit in every context.

Delayed onset of adulthood, caused primarily by the bad economy. Instead of going out into the cold hard world, more young adults are opting just to stay at home with their parents into their twenties & thirties, like a extended childhood.

Because "woman" has now been degraded by idiots all over.

And I prefer to call females my age "girls"

Because they do not accept that they ugly.
