Most Helpful Guy
My main coworker is a married woman, and I know nearly every detail of her private life because I'm available for her to talk to 8 hours a day, 5 days a week. I know about her son's grades, her husband's job, her parent's health, her doctor visits. I know when her house is a mess, I know when she's on a diet and when she falls off the wagon. I know about her exes.
I'm not involved with her or interested in her. It's just the reality of my life that I spend more time around her than I do my friends or family.
