I wonder at your objection to a hamster when you deny almost none of Miss Weasley's wishes. The rodent would scarcely be a significant addition to Lake Cottage's sizable bestiary but it would be an important acquisition for Miss Weasley. I sense that she, like Regan, likes to take care of things, to tend to them. Not a bad disposition to cultivate as it fosters dependability and a sense of responsibility. A hamster is easy to take care of, even by someone as young as Miss Weasley (with close supervision). A word of advice, when picking out the hamster try and shield Miss Weasley's young eyes from the guinea pigs. Regan went insane the first time she saw the fluffy creatures. She waged a long, patient, often noisy, and ultimately victorious campaign to get Rupert Pig and Snowball Pig.
I shall be at Lake Cottage tomorrow. We will stroll over the verdant grounds, watch the surface of the lake rippled by vernal winds, sigh over the first spring buds, fill our lungs with pollen, crown each other's head with daisy wreaths, and talk about Ron Weasley.
Love, Blaise
P.S. Please convey to Miss Weasley my gratitude and admiration for her charming correspondent and artwork, sentiments upon which I will elaborate in person tomorrow.
