I take a nostalgic trip back to a late sixties movie "桃李滿門"
"But how do you thank someone" 和 "taught me right from wrong"

只記得這兩句歌詞和電影最後 ending 是 Lulu 唱這首歌
意I思A ( 知識長 ), Thanks for sharing.

Part of lyrics ("To Sir with Love"):

"But how do you thank someone
Who has taken you from crayons to perfume?
It isn't easy, but I'll try"

"A friend who taught me right from wrong
And weak from strong
That's a lot to learn, what
can I give you in return?"

grow up = 長大成人

~ Thank you for witnessing our growing up.
