"I love people who play guitars on roofs!" said Rose, hopping along the pavement in one of her sudden happy moods. "Don't you?" "Never knew anyone else who did it!" "Don't you like Tom?" "Of course I do. But I don't know about all the other guitar-on-roof players! They might be really awful people, with just that one good thing about them. Playing guitars on roofs... or bagpipes... Or drums... Sarah would like that, and Saffy could have the bagpipes! Caddy could have a harp.... What about Mum?" "One of those gourds filled with beans!" said Rose at once. "And Daddy could have a grand piano. On a flat roof. With a balcony and pink flowers in pots around the edge! And I'll have a very loud trumpet! What about you?" "I'll just listen," said Indigo."
