Totally agree!

Now I've realised what her behaviour was about, it's all slotted into place. Only a few people in the office had anything to do with her. Luckily, she didn't quite wage war on me when I told her to back off one day but did complain to colleagues who she thought would listen.

The male colleague mentioned had a car accident; I was first person he called after trying to get hold of his wife. Although he returned to work quickly, obvious it had affected him. When she asked what was wrong with him, I stupidly told her. A few weeks later, someone ran into her. When she mentioned she was struggling with aftermath (although not injured), I suggested she went to counselling. Big mistake; nasty comment about helping him but you can't help me.

Yes, definitely a narc...
