One of my co-workers is planning her wedding and she won't stop talking about it in the office. She sits in the cubicle next to mine and I swear she is on the phone with vendors and her mom half of the day. When she's not using work time to plan, she's sticking her head above the divider and asking me for advice or sharing her latest ideas. I got married three years ago and know how exciting, fun and busy it all is (and how hard it is to schedule calls during work hours since florists aren't open after office hours), but I frankly can't have her distracting me. I have work I need to get done. How do I tell her she's being distracting without being a buzz kill?
