I worked with a low life pathological liar before she transferred out, and one of the whoppers she told us all was that one of her parents had cancer and she had to take off work frequently to help with doctor appts etc. I have no clue if she was involved in an A or not.
Anyway, our dept sent a Thinking of You card to the one parent who had cancer, and expressed our best wishes and said we'd keep them in our prayers. We actually mentioned that we were sorry to hear of the cancer diagnosis.
The day after her parents received the card, the pathological liar came in, fit to be tied, angry and steaming, and curt and with a nasty attitude. We found out she was lying about one of her parents having cancer, but what could she say? That she lied about it so she could have time off to do whatever?
She was, and probably still is, a nasty piece of work.
