DEAR HARRIETTE: There is a new girl at work, and although I have been nothing but friendly and helpful to her, she has this annoying habit of talking to me as if I'm the newbie in the office. Sometimes she even goes to the extent of explaining things that I already know like the back of my hand. I’m very good at my job, and I’ve been promoted several times since I started working here nearly four years ago. I need to have a serious talk with her about why she feels the need to explain things to me. How should I approach her about this? -- You’re the Newbie
DEAR YOU’RE THE NEWBIE: Stop letting this co-worker get under your skin. You know your job. Be confident in that. When she starts with her explanations, you have a few choices of how to react. Choose one depending on the nature of the moment. You can ignore her completely. Do not respond. Do not react. Just continue with what you were doing. You can challenge her a bit. Ask her if she is saying these things out loud to remind herself of how to do this task. (It's true that some people learn better that way.) You can interrupt her and pivot the conversation to another subject. Or you can walk away.
