Why is it ironic that Anse talks about Jewel's disrespect for the family?

In Section 26, narrated by Anse, we once again have Anse offering a type of evaluation and criticism of his children, but we know from previous encounters with Anse that he is totally incapable of understanding any member of the family. For example, he is annoyed that Jewel brings the horse on the trip with him. He feels that out of respect for his dead mother, Jewel should not ride the horse. But as has been noted earlier, Jewel uses the horse as a symbol in replacement for his love for his mother. Having the horse with him is Jewel's way of expressing his love, and Anse totally fails to understand the connection and can only think that it is disrespectful, when in reality it is Jewel's acknowledgment of his grief and love. Anse's view is ironic because, later on, it is only by selling the horse that they can continue on the journey.
