Edna and Jimmy were engaged. She had had her hair up for a year and a half; they had been publicly engaged for a year. But they had known they were going to marry each other ever since they walked in the Botanical Gardens with their nurses, and sat on the grass with a wine biscuit and a piece of barley-sugar each for their tea. It was so much an accepted thing that Edna had worn a wonderfully good imitation of an engagement-ring out of a cracker all the time she was at school. And up till now they had been devoted to each other.
