Koly is planning to escape Sass with her silver earrings.
As long as I have my silver earrings I can escape.
When Koly was left by Sass in the widows city because of Sass.
Stay here, I will come back to find you once I finish my job.
Raji hadn't come back to see Koly after their talk at the river.
I hope Raji comes back soon.
When Hari and Sassur died, Koly was left alone with Sass. Chandra had gotten married and so Koly has no one left to tell her problems too. However, Koly has hope that she will escape Sass with the help of the silver earrings. With doubts, she knows that she won't be able to escape straight away, but she said "As long as I have the thought of someday, I could stand Sass's scolding."
Even if Koly had known that Sass would have left Koly, she never gave up hope that Sass would come back for her. Koly waited at the railway station for Sass everyday.The rickshaw boy, Raji, told her that he would bring Koly to a house to live in, which gave Koly hope.
Ever since Raji had brought Koly to the river to tell her about his house in the country, Koly had worried if she said something to anger him because he didn't come back to learn to read the next day. Everyday Koly waited in the courtyard to find Raji, but she never saw him. She never gave up hope, and Raji eventually came back to propose to Koly
