Sforno on Genesis 37:11/ספורנו על בראשית ל״ז:י״א

1ויקנאו בו אחיו, they attributed such aspirations by Joseph to the fact that their father had appointed them as senior to them, otherwise he would not have dared tell such dreams even in his father’s presence.

2ואביו שמר, he remembered it because he thought that the dream reflected what would in fact occur. In fact, his father was looking forward to the fulfillment of Joseph’s dream. This reflects the statement in the Talmud Sanhedrin 105 that a person may be jealous of everyone except his students and his children.
