Hot buttons are those that, when people push, you turn red and out comes the anger, resentment, insecurity, and other negative emotions you wish weren't a part of your life.
In said state of skillful yielding an overwhelming joy comes upon you. If one trait above all others presents, (and it will) it is constant laughter. During times of stress freedom I have noticed that every thing becomes funny. The constant bombardment of thought becomes - funny; spilled milk funny; the sleepy egocentric unconscious reactions of others-riotous.
