This was initially my thought as well; I felt that way for much of my life. Then at some point in my 20's I got a little more into the concept and came up with this: It was only the 'grass is greener' syndrome. I had to come up with a more thorough description of what a girl's daily life was like. And even then, I was willing to accept the negative things in order to 'get' to be the girl I thought I was supposed to be. Until.......I realized that I was simply exchanging one set of difficulties for another. A woman's life is definitely different. In brief; wake up earlier EVERY SINGLE DAY because it takes more time to take care of all the details of appearance and hygiene as a girl. You're looking at about an hour earlier a day.....of lost sleep; make up, clothing, etc.. Stepping out of the house, girls have to be aware of the safety factor that men routinely ignore. If you decide to wear a skirt or dress, there is the constant readjustment of them to avoid exposing yourself. Bra straps too need to be adjusted, whereas tshirts for guys need well, nothing, if they're even worn at all. Watch where you put your purse if you want to keep all your belongings, and also not damage anything in it, as well as avoid anyone else accidently doing so. Of course, carrying a purse everywhere when you're carrying anything else becomes a chore too. Love the long beautiful hair? Try to keep it out of your face, mouth and food (as well as during sex, keeping it out of other things as well). Every time you go to the bathroom, you have to check up on make up, hair and how your clothing is situated, whereas a guy just goes in, pees, occasionally washes his hands, and leaves (and yeah, lots of guys don't wash their hands; if you don't have any diseases and are normally clean, you can probably get away with this without any problems). Many women suffer from stress incontinence, or incontinence in general, for those who don't know, that means unintentionally urinating. Happens all the time, but they won't tell you about that, it's one reason lots of women wear panty liners or pads all the time. Lets not forget the problem with getting runs in the stockings by merely rubbing against anything that has ANY tiny rough thing protruding; even the tiniest splinter from what appears to be a finished part of wood furniture can do it. Eating, virtually every woman has to 'diet' constantly. See what the western hemisphere has become by women ignoring this by stress eating at the workplace, obesity has become an epidemic. So you can't eat what you want to. Of course, we cannot forget the one week a month of bleeding and cramps, now, can we. Surely that must be fun, right? Every female I've ever been with for more than a few dates has at some point been in the situation where she didn't have the 'female hygiene product' that she needed at an inopportune time, and either wound up stuffing her panties with tissue or something to go to the store, or sending me out on the errand (more fun, right?). Coming home from work, being expected to be a good cook and make something delicious every single night. For decades on end. Laundry, delicates, whites, light colors, darks. Hand washing certain things, laying them out to dry. Ironing. Washing herself? How many guys clean the tub? How often? Girls have to keep the tub clean, or risk infections you-know-where. So they have to scrub the tub, and everything around it, often. Of course lets not forget shaving every inch of skin below the scalp hairline. I don't know about you, but I can do my face in about a minute while in the shower. I'm sure a woman's body takes longer than that, not to mention the various contortions she has to go through to SEE parts of herself to shave.
Hair. Her hair takes time; the ends of it are about a year old, and of course require different care than what's new and closer to the scalp. So washing and conditioning is a complicated event. Not to mention drying and styling. Which is different, depending on the humidity on different days. How often do you think guys have 'bad hair days'? Not too, really. But happens to girls all the time, and they stress over it.
How about nails? Girl comes home, has dinner, does some chores, sits down and does her hails. Stuff happens; now, does she take care of it and have to do her nails all over again? Yup. Guys just wash our hands and we're done; what, a minute? For a girl, that's two hours of time to get the hands right again, polish takes time to dry hard.
There's more. That was just some of the routine parts of a day.
Edit. Oh yeah. Thinking like a girl. You mean care free and focusing on clothes, dates, fun, right? Lets not forget the hormone influenced mood changes, feelings driving thoughts instead of facts (woman's intuition, right?), difficulty with directions being misinterpreted because men 'see' the world better in 3 D in our heads (women tend to focus on landmarks and direction changes, not on distance or compass). I can't even begin to ponder all of what seems to us as nonsensical rambling discussion about nothing in particular, which all women seem to do constantly.
