The lesson in this chapter is: “Tell the truth. Don’t lie”. (Or we have the same idea in the Commandment “Thou shalt not bear false witness against thy neighbour”).
This story was like a gift of the step-brother for her dearest younger sister when they lived far apart from each other. In the beginning, the family relationship was not good, but then they secretly helped and protected each other in their lives. When they grew up, they went to different states of Canada and the brother missed her sister so much. That’s why he included these illustrations in the letter he sent her.
I hope they still keep in touch and remember each other. The story was a secret so I can’t tell you more, but I was so moved when reading it.
