You're right, it isn't your fault she went home.

Yeah sure, maybe she had a hard life. But you know what it sounds like to me? She's a spoiled brat. Calling her mom in tears because someone confronted her? That's not hard life, that's "mommy will take care of me, boo hoo." Sounds like she only puts on her big girl panties when she wants to boss people around.

If Angelica from Rug Rats was a real person, I feel she would be your co-worker..... She has excuses for everything. She bosses everyone around. She makes life miserable. She's a bully. There is no question about it. And the second someone actually stands up to her she goes boo hooing away....

You did the right thing, Anika. If your work doesn't see that, then it is a toxic environment and you shouldn't be there.
