How does that affect my relationship with my wife? We both have been able to be very honest with each other, and we have a relationship built strongly on trust and honesty. I hope I never break that because it would be a betrayal. It is really about the tone used to express the thought if the thought is important enough to express in the first place.
I despise the whole concept of "white lies". I despise people who dare to manipulate me, to condescendingly see after my own good or feelings by bald-face lying to me about something. Be honest or say nothing, but do not dare tell me excuses that are obvious lies, "socially acceptable". According to whom? Where do you draw the line between "white" and "black" lies? I do find it insulting, and I often do not mind calling people out on it; sure, things get uncomfortable, but they are the ones spouting deceit.
Perhaps it boils down to the notion that what somebody expresses is a measure of their integrity and honor. Somewhere I read a quote along the lines of... You can judge a man by two things: what he wants and what he is willing to do to get it.
