I'm the same way and all but one of us inherited my mothers smallish frame. Besides, it's not about the size of the body but the health of it.

Body dysmorphia is more rampant then even you may suspect.
In some cases it's life threatening.

Fact is Kathleen, you're a 'babe' and respect intended add this to your age. By that, you don't look it and I think you are an extremely attractive lady.
Some women are better looking for having curves and wobbly bits, others are amazing through being lean and toned while those who are between can be beautiful too.
In the end, perfection is subjective.
If I were better toned and fitter than I am, together with living closer to you, I would be proud to be your 'toyboy/toybloke'

Stick to your guns; lean (I prefer that term to thin) and fit is hot; lean + fit + smart = the hottest. And muscles are fine - I think the women at the CrossFit games are beautiful, often stunningly so.

Seems like a person just can't win. If you are are overweight...you are fat shamed. If you are underweight...you are skinny shamed. If your body proportions are "ideal"...you are attacked for some other "societal offense" such as hair style or overbite, large feet...ANYTHING that will make the person who is doing the "judging"...feel better about themselves. Flipping through YouTube the other day and of course TikTok has their feeds all over the media sites ... I come across some young girl, sitting on a set of stairs, just showing off her good looks. This is what society has been reduced to...this is the younger generations WHOLE LIFE. Selfies that draw massive amounts of "likes" are the driving force behind our "future leaders". It doesn't matter that they couldn't think their way out of a wet paper bag if someone handed them a "lit blow torch" and said, CUT HERE...All that matters is adulation, regardless of how they get it. It is "Brand Building 101". What is NOT different is the fact that the same thing went on with each generation, simply a different form. I have a high metabolism...as a result I fell under the "skinny kid" category my whole life. I learned a long time ago to just laugh and walk away(the rebuttal insults that went on in my MIND on the other hand would have stopped the offending parties heart). Maintaining weight is a challenge for people on both ends of the spectrum. It is not an excuse to project ones insecurities. Unfortunately projection is championed by the very people we put in positions of authority. Which begs the question, "How do we fix a problem that has become a RALLY CRY for the very people...who are charged with fixing the problem? It's the "fox in the henhouse". We work with the genes we were born with. Fight back when you can...know when it is a lost cause...look for opportunities to redirect the neanderthals. We can improve and tweek and move the bar a little higher. Ultimately we will achieve our best when we accept and work with what we have. And to those who like to body shame...FUCK OFF.

My guess is that you reminded the overweight out of shape woman of her physical state and she could not bear it. In a state of envy she lashed out at you with an unwarranted and nasty comment on your physique. You look in great shape and no doubt you are envied by other women.

All I can say is; I am jealous.

You could try: what allows you to think it's ok to make comments on my body? I've always found questions to be far more powerful than statements or insults because they seem to strike deeper (even if it's; were you born an arsehole or did it take practice?)

I feel you pain because I’ve been thin my whole life. I’m 73. As a child, My mother tried to fatten me up with a raw egg in a milkshake. People have made comments about my thin legs. One gal told me she’d never date a man like me because I wasn’t big enough for her. We’ll she was easily 50+ lbs oversight but I kept my mouth shut. How rude can you get?
I’ve accepted my body. It’s the only one I’ll get. However, in order to do my chores around my property, I keep my muscle strength up with weight and resistance training. For fun I run. I especially like running hills for the challenge.
So, keep up what you’re doing and stand up to the “skinny” insults. You’re not a door mat. Good luck

Go into the bathroom, look in the mirror and practice saying, "Fuck off". People should learn manners and stop judging women on their bodies.

While you are there tell yourself how fabulous you are.

I've been called skinny many times in life and I don't like it. I believe people think it's okay to body shame a lean person and not a large person.
Calling a person skinny is just as offensive as calling someone fat.
Criticizing others shape is cruel and immature.
They would think that we're wrong if we give it back to them.

Men ought to get body-shamed more.

That IS bullshit.
