Then she would fetch my wooden slate. She had already washed and washed and plastered it with yellow chalk. She would take a tiny earthen ink-pot and a red pen. She would tie them all in a bundle and band it to me. After a breakfast of a thick, stale chapatti with a little butter and sugar spread on it , we went to school. She carried several stale chapattis with her for the village dogs.

My grandmother set inside reading the the holy book when we had both finished, we could walk back together.
