I think TC just likes being angry.
She/he thrives on drama. She expresses how angry she/he is by

faces.

As a professional and an adult I tried to have her call me, not to get her to understand but to see if she can have a conversation without the insults.
She refused, and would rather ask for people's thoughts so she/he can turn around and attack you personally,than have normal dialogue, enough said.
Things are different with Travel Temptress/Bruce and others b/c unlike TC they can speak without getting all emotionally charged and theyremain professional.
I would take advice from TT and Bruce anyday b/c I respect them. Can't say the same for TC...maybe when she takes a chill pill, we'll see.
