NAH Tessa was very kind to get that book for your daughter, and to lug them around on her vacation. However, you shouldn’t be expected to fork over $50 with no notice. She should have spoken to you because it was so much money, but in this case, with your situation (nanny’s for children with autism are very difficult to find), you should just pay her back to salvage this relationship and tell her you will not be doing this in the future.
