"You just think you're better than us" is something I hear from time to time, but never from anyone I've talked with.
It's shouted at me from throwaway accounts operated by strangers.
And I find that very amusing, to be honest. If I were to correct them, would that not be exercising a perception of superiority--the very false notion I'd be hoping to dispel?
What a conundrum!
My choice when faced with this sort of interaction has been to try to understand where the other person is coming from, but they never elaborate on why they believe that.
