You’re right. But until you’ve lived life as an unattractive girl or old woman, you can’t really say. Again, that’s why beauty, fitness, plastic surgery, etc are booming industries.To each their own, just not how I was raised so it seems vain, people treat you differently for a variety of reason, you shouldn't change yourself for others.
If majority of people weren’t vain or concerned about the different treatment they receive, people wouldn’t pour their money into them.
