I'm going to tell people at work what really happened the night I hooked up with a co-worker
What really happened that night and why do you want to tell people about it?
It was the best moment in my life.
You should keep that to yourself and not share with others. Think about how she would feel if you shared things like that.
I don't care, I need to return the favor she did to me.
Usually people keep this kinds of details private. People may be offended if you start talking about it publicly at your work.
