I suspect she doesn't like to be corrected in public, as Hanoi John did in Arizona. When Teresa spoke to the people gathered, she said something like "It's great to be in Nevada!", at which time Hanoi John leaned over and whispered in her ear that they were in Arizona. She then corrected her mistake...
I'm surprised John had the cajones to correct Terry. He's been quoted as saying he let's what she says stand on its own.
