OK. Since my last post, things have settled down nicely as regards the guy in my office. He's just been getting on with his work and has backed off.
Yesterday, my female co-worker told me, "By the way, he asked me why you're wearing boots (I was wearing ankle boots) today (meaning me)". She said back to him, "I don't know. Why don't you ask her yourself". I said to her, "What has what I'm wearing anything to do with him or my work performance"?
He's not my senior btw, just on the same pay bracket as me and in the same role.
Why is it his business to question what I wear now? I feel I've committed a terrible crime just because I had ankle boots on.
