A man once asked another man to lend him his raincoat. It was immediately given, but at the same time the giver was very much annoyed that the other should have asked for it, and when he himself was obliged to go out in the rain he was vexed at having to get wet. It would have been much better for him to have said at once that he was sorry not to be able to lend the coat. Once having given it, however, he should not have grudged it, but should have been glad to get wet having helped the other man; if he gave it he should have done so with his whole heart.
