Yes I was talking about aleph_minus_one's post, apologies for the confusion (I got a bit mixed up). Unfortunately it's too late to edit it.
In terms of the social dynamic I agree with you, the "white lies" serve as a way to be considerate of the other person. And it's not just "lies" about them either, if someone is in a hurry or in some casual context and asks how I am and I've had a shitty day, I might say "I'm fine" to avoid them feeling the need to talk through my problems with me. If someone asks at dinner and I spent the morning having explosive diarrhea, I don't share that either. That is a classic white lie but to see that as a betrayal strikes me as extremely bizarre.
