There are phrases I have learned to look for. "Of course, I wouldn't expect YOU to ______________." "You are obviously intelligent/well-read/well-intentioned, but you are not an expert." "You will find that, when God is really in your life, you won't _________________."
Sighs, the tendency to speak as one would to a child.
Phrasing things as orders or threats, rather than requests.
Would you like some serious advice?? Don't get too good at finding it. You are going to find all kinds of people who think they are better than you-- medical professionals, social workers, teachers, therapists, average people on the street. If you don't see it, it isn't depressing. If you do see it, you stop wanting to leave your house.
Because there is nothing you can do about it. If you make a mistake, they take it as proof that you really are lesser. If you show them up, they either ignore it or become vicious. If you try to reason with them, it falls on deaf ears.
If you are going to recognize that attitude, honestly, your best bet is to learn to exploit it. Prevail upon their superiority to get the help or advice you need through flattery and pity.
It reduces the hell out of you-- but hey, if you can't beat 'em, join 'em.
