He used have genuine stories to tell, funny jokes to elicit laughter, and sound advice to dispense. Then we got promoted.
His stories started having outlines of little white lies, his jokes tried too hard, and his advice became condescending. He started strutting around (in the worst possible way) with overconfidence that, frankly, I pitied. So we started forgetting to call him for coffee breaks, stopped passing our lunch boxes, and being vague about weekend plans.
