Answer:
She thinks he is too ugly and too small.
Step-by-step explanation:
This question is about "The tale of Despereaux" where we know the story of Despereaux, a mouse very different from ordinary mice, both in appearance and in personality. Despereaux was born very small, smaller than all the mice ever seen in the world and has very large ears, disproportionate to his body. This makes Florence, his aunt, find him strange, ugly and too small, she doesn't like anything she sees and doesn't bother to tell everyone to hear that Despereaux is smaller than any mouse in the world and has obscenely large ears.
