This is meant for black and white people only. Feel free to disregard if you're Hispanic or Oriental.

You 5'7" men are NOT average size. You are short. It might be average size for the WORLD, but that average includes everyone, probably including pygmies, and definitely billions of orientals and hispanics. They drag the human average way down. And then, there are malnourished people all over the third world. The people who go around proclaiming themselves to be "average height" almost certainly never fall into any of those categories. The "average height" for a white or black adult male, born into a civilized society, is almost six feet tall.

If you're below 70 inches tall, deal with it. You are short, and this Elizabeth Warren/Rachel Dolezal mendacity regarding your height status doesn't alter your ability to interact with objects on top shelves.

And sorry, ladies, you are also short. "Tall for a woman" is a consolation prize, and consolation prizes are euphemisms for failure.
You are a malformed gender which primitive people speculated was invented to punish the rest of us, built to the specifications of a biological specialization, surviving by the exploitation of unfortunate endocrine responses in the more generally functional variant. Things are not made "too high", you are simply too short to utilize optimal designs. Stop making subjective accusations under the guise of requests for assistance. Decent people of proper stature should be perfectly happy to assist you, as they would in reading a sign for a blind person., or writing things out for a deaf person, your belittling efficient storage arrangements does not make the request more persuasive.

And BTW, short men (and aberrantly normal-sized women), there is nothing wrong with unorthdox size comparisons in a couple. If you are really THAT insecure, chances are you could still take her in a fight, if it ever becomes necessary . Also, it's not an excuse to get pissy about her footwear making her taller than him. That should only be a problem for that narrow intersection of people too stupid to understand how high-heeled shoes work AND who think that personal compatibility is so easy to obtain that it is less important than the relative sizes of males and females.

That leads me to wonder, do homosexuals have those issues? I have never quite understood why they seem to so often ditch the most appealing part of their lifestyle/orientation - not having to put up with the opposite gender's peculiarities - in favor of partners who most closely match said peculiarities. I would think one of the joys of cohabiting with a man would be an end to concerns about drapes or having decorative crap cluttering up utilitarian surfaces. But apparently not. Same thing for lesbians - is WNBA widowhood superior to NFL widowhood? The real NBA plays five times as many games as the NFL, so I can't imagine it's much of an improvement. So with that in mind, is it more acceptable to men to have a male partner who is 6'5" to your 5'10" than a woman who is 6'1"? Why? You are even more likely to lose a domestic violence incident in the former pairing. For women, do you feel better about dating a woman who is eight inches shorter than a man who is two? You are still towering over her, you are still unlikely to feel safe or reassured in your partner's company (that was the reason my grandmother once gave for why she would never want a short husband), and so on.
And if it IS an issue, does that mean homosexuals try very hard to find partners of close sizes? That would also have the beneficial side effect of allowing them to share clothes. Back when my brothers & I all lived together, sorting out the laundry and not getting clothes mixed up with a troublesome issue at times, because we are just similar enough in size that it is difficult to spot-check clothing size differences, but not close enough to easily share clothing. And with underwear, the fit is not as important, but even less appealing to put on someone else's by mistake. But why would sharing underwear be a problem if the stuff underwear covers up is overlapping from time to time?

Glad we got that straightened out.
