Switching His Father's Requests

When Chiya, his son, grew up,
he would reverse the requests.
Rav asked him to convey to her,
so that Rav would get what he wanted.

Rav	Your mother has improved now that you convey my requests.
Chiya	It is I who reverse your request to her.
Rav	This is an example of the very popular saying that people say: He who comes from you shall teach you wisdom. I should have thought of that idea myself.
