You don't have to respond. That is just rude. Let the parent know you'd be glad to set up a meeting with the principal present, and that you have to end the meeting now. You can say something like this, "I think this conversation should be continued with the principal present," and then stand up and offer your hand. It should be obvious that you are ending the meeting. If that doesn't work, then state that you need to be headed somewhere else but you will follow up with them after you've made sure the principal can join you. Then fill your principal in as soon as you can. Remember, she hired you, so she has your back. Be honest with your principal about what caused the conversation. She will most likely want to help you out and will not tolerate parents to talk to her teachers like that.
