How does Frederick Douglass feel about his new mistress when he first comes to the Auld's home?

He is happy to find that she is kind and gentle with him

When Frederick Douglas came to Auld's home for the first time, he was stunned by the extraordinary kindness of his new mistress. Mrs. Auld had never had a slave before, and she looked like an untouched by the evils of slavery. She did not mind him directly looking into her eyes, and she did not appreciate the fact that he was submissive. She taught him alphabet, and some small words. When Mr. Auld noticed what she was doing, he demanded that she stop immediately. The reason is, education breaks slaves, making them unbearable and unhappy. When Douglas heard it, he discovered the strategy that white people use to enslave black people. Douglas is grateful to Hugh Auld for this enlightenment.
