A coworker is VERY offended that I wear a headphone at work, she thinks that I do this because she talks too much. She is half right. I don't mind if someone talks a lot but I do mind constant complaining and oversharing personal information. She constantly complains and she is overly negative, I do not need that negative energy in my life. Every time she has a fight with her husband, she will tell everyone in the office the next day whether you want to hear it or not. Her problem is your problem.
