For me they do.
I become very anxious about upsetting or disappointing the other person.
This translates into me avoiding saying or doing things that I'm not confident about getting right.
This, in turn, upsets the other person, because it appears to them that I don't care to do or say those things - when, in reality, I care very much, but am paralyzed by fear.
My anxiety causes the exact thing I'm trying to prevent. They get upset, and I disappoint them.
