There was a yell of rage from Michael, and "O father!" Wendy
exclaimed.

"What do you mean by `O father'?" Mr. Darling demanded. "Stop
that row, Michael. I meant to take mine, but I -- I missed it."

It was dreadful the way all the three were looking at him, just
as if they did not admire him. "Look here, all of you," he said
entreatingly, as soon as Nana had gone into the bathroom. "I
have just thought of a splendid joke. I shall pour my medicine
into Nana's bowl, and she will drink it, thinking it is milk!"

It was the colour of milk; but the children did not have their
father's sense of humour, and they looked at him reproachfully as
he poured the medicine into Nana's bowl. "What fun!" he said
doubtfully, and they did not dare expose him when Mrs. Darling
and Nana returned.
