I think that person has run into too many people that just have no idea of the concept of fairness and respect. And I can't blame them, either. I've seen more than my share of them.

Some people treat respect as dealing with strangers like this: "I'll be decent to you, you'll be decent to me"

But some out there, frankly far too fucking many really, treat respect as authority: "If you don't treat me with the respect I think I deserve, I won't treat you like a human being"

And those people, sadly, are too fucking plentiful.
