the last month or so of my job. recall a past stressful moment and how the belly grew into knots. if you are painting a slick surface, this is too long, youd need a 1/4-inch nap; likewise it is too short for painting brick or cinder block, youd need a 3/4-inch nap. often when things don’t go the way we planned we assume something is wrong with us or our lives. but it’s what’s going on in your head that’s scary.
