How on earth am I supposed to get through my 1:1 meeting with my boss Thursday morning? Do I address the elephant in the room, ie, that I went to HR. Or do I pretend it doesn't exist, smile, and stick to business? And, what if she brings it up? I don't want to engage in any conversation about it with her while it's all under investigation.

I have no clue how to handle it. Any advice?
