She is very rude to him, dismissive in attitude and I'm sure tone of voice.

He has to have a response, and I've had to deal with the type. Its harder than it looks. You don't want to stoop to that level with them, but if you don't you take alot of shots. It will drag you down unless you really don't care at all what they think. If they get a crowd, they can cause you alot of trouble.

It may be in the end, "I don't want to go there with you", and she's saying "I don't want to meet you in the middle". Time will tell.
