Mrs. Thornbury went with them to the gate, trailing very slowly and gracefully across the grass and the gravel, and talking all the time about flowers and birds. She told them that she had taken up the study of botany since her daughter married, and it was wonderful what a number of flowers there were which she had never seen, although she had lived in the country all her life and she was now seventy-two. It was a good thing to have some occupation which was quite independent of other people, she said, when one got old. But the odd thing was that one never felt old. She always felt that she was twenty-five, not a day more or a day less, but, of course, one couldn't expect other people to agree to that.
