The parent's joy is personal and deep — 'even mine' emphasises that this is not a formal obligation but a heartfelt response. Wisdom in a child does something to the parent that nothing else can do. This is one of the most tender verses in Proverbs.
Memory phrase: Wisdom brings parents great joy.
Talk about it: How does it make your parents feel when you make wise and good choices?
Prayer: God, help me grow in wisdom and make my parents glad.
