Most Helpful Girl
I have a hunch that it's for the mostpart, a matter of people just having ideals, but can't really explain it.
It grinds my gears to no end when someone tell me that I 'deserve better' than my boyfriend. I'm just like... what? Perhaps in certain contexts, he's a bit of a douche.
But by holding onto that logic, you could apply it just the same that certain races/religions/genders, etc., of people are entitled to being with someone 'better' than others, solely because of who they were born as. Which would also require a universal outline of what makes someone more or less desirable, which doesn't exist and is a very subjective type of thing.1
