What do Tea Cake and Janie do in the middle of the night to "make use of the moon"?

Tea Cake tells Janie that the moon is too beautiful not to enjoy it. He suggests that they go fishing. Digging for worms by lamplight is so crazy that Janie feels like a "child breaking the rules." They catch a few fish, and then they have to smuggle Tea Cake out of the back gate so that Janie's neighbors won't gossip.
