In the Mood for Love (2000)

 

Chow Mo-wan: In the old days, if someone had a secret they didn't want to share... you know what they did?
Ah Ping: Have no idea.
Chow Mo-wan: They went up a mountain, found a tree, carved a hole in it, and whispered the secret into the hole. Then they covered it with mud. And leave the secret there forever.
Ah Ping: What a pain! I'd just go to get laid.
Chow Mo-wan: Not everyone's like you.
