回复：既然自己没做什么坏事，也不用害怕真相吧。

you have self-conscience. Not everyone is like you. Some American are very mean.

the lower manager was actually not my orginal manager. I originally had only 2 bosses.the middle manager brought her in and create a manager position for her.She was only in charge of me.

So, I am gonna just write: organization restructure. It is true that they changed the person I reported to.
