Scared to be in the same room.... don't know what you'll do.....

Yeah, I've come against the same crap. I've had people say they are "afraid" of me because if I'll SI, what stops me from harming them or one of their loved ones as well? Duh, because the S in SI means "self" not "others."

This situation needs dealing with. That person shouting at her needs to be reported to a superior. It was entirely unprofessional conduct.
