I have a few problems with that.
The depiction of the girl in the song when I was in 5th grade drove me crazy. Our teachers told us all how were were supposed to look. Bras weren't cool. Curves weren't cool. Because that meant other things were happening, whether or not we wanted them to. The boys were relentless to us for these things.
I didn't want boys calling me all the time - I didn't like most of them. My opinion of many of them never improved.
Since several of us had already started having zits, our idiot clever teacher switched "a pound and a half of cream on my face" to "a pound of Noxema on my face". Yup, feeling lots better about that! Sure glad I'm a girl.
Dresses made of lace. Puke.
We had to learn actions to go with this song. Because it was cute and that's what girls do.
Our dads were sitting in the audience and very aware of why we were singing this stupid song.
That just made everyone uncomfortable.
Over the next few years, there were increasingly fewer reasons I enjoyed being a girl. Love it when I had a deep cut four inches long above my ankle trying to shave. Yanking individual hairs out of my eyebrows is a kick. Hormonal imbalances just make me giggle with delight (BTW how come guys hormones don't ever get out of whack?). And don't even get me started on boob issues. And I get to enjoy all these wonderful delights for 20 more years at which point I'll go into menopause, whether or not I WANT to, and get all sorts of fun new things to enhance the "girl" experience.
Therefore, it seems to me that the only way for things to be fair is when MEN write songs about what they like about girls and say it's what we like, they should be able to have a personal experience of how much fun it really is.
