Don't give in. Reality building should not be a spectator sport. Validation is for people who are unsure of their truths or too sure of their lies.
Nobody can claim supremacy over your reality - only you. Your reality is constructed of emotions much more than anything you touch and see and hear. Your emotions allow or dismiss what you perceive. Your emotions validates the input of one person and discards the input of another. You do play some role in building the reality of another person, but you have no control over how that person uses your contribution. An insult is never given, only taken. Same with a compliment. Reality truly is in the eye of the beholder. (t.y.m.)
