My boss did not reply to a message of mine yesterday even though she was online and "green", meaning available all afternoon to reply to me. I suspect that she wants to let me know that despite us seeming to get along on the surface, that she still doesn't like me.

I was bothered by it last night. This morning I'm just like, whatever... that's her issue, not mine. I had every right to speak to her boss and his boss about her poor treatment of me. If she doesn't like that, well, grow up and be a professional adult. She is behaving like a child - it's very passive aggressive behavior. And that's ALL on HER. So... whatever.
