For your amusement

I sometimes feel a little uneasy about that imagined self of mine--the Me of my daydreams--who leads a melodramatic life of his own, out of all relation with my real existence. So one day I shadowed him down the street. He loitered along for a while, and then stood at a shop-window and dressed himself out in a gaudy tie and yellow waistcoat. Then he bought a great sponge and two stuffed birds and took them to his lodgings, where he led a shady existence. Next he moved to a big house in Mayfair, and gave grand dinner-parties, with splendid service and costly wines. His amorous adventures among the High-up Ones of this Earth I pass over. He soon sold his house and horses, gave up his motors, dismissed his retinue of servants, and went--saving two young ladies from being run over on the way--to live a life of heroic self-sacrifice among the poor.

I was beginning to feel encouraged about him, when, in passing a fishmonger's, he pointed at a great salmon and said, 'I caught that fish'.

LOGAN PEARSALL SMITH, Trivia, 1918

With a change of the pronouns and a few other details relevant to the sex of the narrator, it appears that the Me of Mr Smith's daydreams is not so very different from CM's own Imagined Self, though hers has never claimed that she caught a fish.
