"If you need it more than I do, Mrs. Sparrow," he said, "I'll give it to you. But you must prove it."
"Why, of course I do. I need it for my nest."
"And I need it to keep me from starving."
Mrs. Sparrow cocked her head sideways and looked queerly at him. "You don't look as if you were starving," she observed. "You're as plump and sleek as any rabbit I ever saw."
"Maybe. But I haven't had any breakfast, and I'm not used to it. This leaf tastes so good I wish I had a hundred more of them."
"Then why don't you go and get them? There are plenty in the park and woods."
"But how am I going to get them?" asked Bumper. "Don't you see I'm caught here in the mouth of the sewer. I can't get out without swimming."
Mrs. Sparrow looked surprised at this information, and flew from her perch on the embankment to a stone below. She cocked her head sideways, and looked all around her.
"What puzzles me," she said finally, "is how you ever got in there without swimming. You can't fly."
Bumper smiled, and shook his head. "No, but I wish I could. I wouldn't stay here arguing with you about this leaf but fly away and get a good breakfast of a lot of them."
