During the first encounter with the
Little Chinese Seamstress, Luo and Ma (the narrator), the "City Youths", are introduced to the tailor's daughter, who is at home when her father is not. Luo asks her to lengthen his trousers, because,
as Ma says, even Malaria won't keep him from growing. They make smalltalk, and eventually Luo makes a bet with the Seamstress that they
have something in common. The Seamstress takes the bet and loses when Luo shows her that their second toes are both longer than their first toe, and thus is forced to lengthen Luo's trousers for free.
