Dodo Wonders by E.F. Benson

Dodo had always firmly believed that boredom was by far the most fruitful cause of fatigue, and since she herself was hardly ever bored, she attributed to that the fact that she was practically indefatigable.

Her immunity from boredom was not due to the fact that she, like the great majority of the women of her world, steadily and strenuously avoided anything that was likely to bore her: it was that she brought so intense and lively an interest to whatever she happened to be doing, that her occupation, of whatever kind it might be, became a mental refreshment. Last night, for instance, at dinner she had sat next Lord Cookham at a mournful and pompous banquet, an experience which was apt to prostrate the strongest with an acute attack of nervous depression, but the only effect it had on Dodo was to make her study with the most eager curiosity how it was possible that any one could be so profound a prig, and yet not burst or burn with a blue flame.
