This married guy started in our office about 4-5 weeks ago. I've been in my role 8 years. Last week he bought me a Kit Kit - nice, OK.
I'm a very private person and never bring in my personal life into work. Now, he's asking my coworker where I live, the exact house and if I have a partner. My sensible coworker told him she doesn't know about my personal life and go ask me himself. He also wanted to know why I didn't say bye when I left for the evening. Our office is busy with 8-9 of us at any given time, so my 'byes' might get lost in the noise and busyness of the office. Plus, I have to rush for my train.
Best way of dealing with him? I don't owe him or anyone any explanation about my life or my ways/actions.
