“It is time for you to go to bed too,” she said to the girl. “Mr J.L.B. Matekoni tells me that you have had a busy day repairing engines.”

She wheeled Motholeli back to her own room, where she helped her out of the chair and onto the side of the bed. She liked to have her independence, and so she allowed her to undress herself unaided and to get into the new nightgown that Mr J.L.B. Matekoni had bought for her on the shopping trip. It was the wrong colour, thought Mma Ramotswe, but then it had been chosen by a man, who could not be expected to know about these things.

“Are you happy here, Motholeli?” she asked.

“I am so happy,” said the girl. “And every day my life is getting happier.”

Mma Ramotswe tucked the sheet about her and planted a kiss on her cheek. Then she turned out the light and left the room. Every day I am getting happier. Mma Ramotswe wondered whether the world which this girl and her brother would inherit would be better than the world in which she and Mr J.L.B. Matekoni had grown up. They had grown happier, she thought, because they had seen Africa become independent and take its own steps in the world. But what a troubled adolescence the continent had experienced, with its vainglorious dictators and their corrupt bureaucracies. And all the time, African people were simply trying to lead decent lives in the midst of all the turmoil and disappointment. Did the people who made all the decisions in this world, the powerful people in places like Washington and London, know about people like Motholeli and Puso? Or care? She was sure that they would care, if only they knew. Sometimes she thought that people overseas had no room in their heart for Africa, because nobody had ever told them that African people were just the same as they were. They simply did not know about people like her Daddy, Obed Ramotswe, who stood, proudly attired in his shiny suit, in the photograph in her living room. You had no grandchildren, she said to the photograph, but now you have. Two. In this house.
