Our family is fairly laid-back. My husband and I are incredibly fortunate that our son somehow inherited all of our good genes and relatively few of our evil ones (and there were lots of the evil ones to go around).
But we all have bad days. Anyone who tells you otherwise is either a liar or has an extreme case of denial. When we have bad days in my house, I like to play the "When my Mother was my age" game for a little perspective. You can play, too (preferably with your own mother or other parent of choice, not with mine.)
