Dear June, About a year ago a coworker and supposed friend of mine betrayed various confidences and otherwise badmouthed me to my supervisor. I am pretty sure this led to my termination. Even if it didn’t, I have no desire ever to see this man—let’s call him Nick—again, and have actually changed my life in a few small ways (go to a different Starbucks, blocked some mutual friends on Facebook, changed food coops) to make it less likely that our paths will cross.
