You grew up together. Fought over who got to ride the newer bicycle and who would have the bigger bedroom. Laughed at the same old TV cartoons while inhaling your morning ration of Kellogg’s Corn Flakes with sweetened milk. Made fun of each other unmercifully. Griped to one another about all of Mom and Dad’s stupid rules. Told lies to help each other escape punishment for breaking those same rules. Or, with unbridled glee, deliberately tattled on the rule breaker in order to see them suffer the penalty from Mom or even worse, (gulp) Dad.
