I was a postman in a remote area of Myanmar. Once a month I went downtown to collect the post and then walked from village to village, which were far away from each other. In each village, I delivered and
collected the post. I also used to read and write letters for the villagers. Most of them were illiterate. I also passed on the news I had heard from the town and the other villages. The people treated me well. It was a hard job but I loved it.

My mother came from Baffin Island. She used to live in an igloo: a domed house built from blocks of ice. The house had only one room for all the generations: grandparents, parents, brothers, unmarried sisters, and sometimes other relatives. Everyone worked together to survive the Arctic winter. Men went out hunting while women stayed at home making clothes and preparing food. When they had to travel far, they rode on dogsleds. At night they used to entertain themselves by telling and acting out stories. They
danced to drum music too.
