Young Arrietty is new to her Aunt Lupy’s (which is hidden behind the lath & plaster of the wall) and she has learned that Lupy makes clothes for another borrower who is seen by everyone else as something of a wild thing – unlike the others he lives most the time out of doors. Homily is Arrietty’s mother.
”It’s very kind of you to make his suits,” said Arrietty …
“It’s only human,” said Lupy.
“Human!” exclaimed Homily, startled by the choice of word.
“Human – just short like that – means kind,” explained Lupy, remembering that Homily, poor dear, had had no education … “It’s got nothing at all to do with human beings. How could it have?”
