Question

how did the grandmother tease her granddaughter when she expressed her desire to read

Answer 1

When grandmother expressed her desir to learn Kannada alphabets, the narrator simply laughed in fun. She did so because she thought it was quite absurd for a woman in her sixties to learn alphabets like a school kid. But the grand mother reacted calmly. She did not argue nor she rebuked the child. She just smiled but kept her determination.
