"What's a subway?" he asked drowsily. "Where is it, Mother?"
"You'll find out perhaps to-morrow, if Daddy isn't too busy," Mother assured him. "Oh, precious, see this poor old woman."
Sunny Boy sat up, wide awake instantly.
An old woman, bent and lame, had entered the car and stood swaying, trying to reach a hanger. She had a worn old shawl over her shoulders and carried a big basket.
Sunny Boy slipped out of his place.
"Here's a seat for you," he called clearly.
The woman sat down heavily, mumbling her thanks, and Sunny Boy had to stand the rest of the way home. Not that he minded. For one thing, it kept him wide awake, and for another, his father always gave every woman his seat in a crowded car, and Sunny Boy was sure he would be glad to hear that Sunny Boy had done the same.
"And what do we do to-morrow?" this same Daddy asked that night as he helped a very tired, sleepy little boy to get ready for bed. "I'm going to play with you and Mother all day, you know."
Sunny Boy was ready with his reply.
"To-morrow," he said indistinctly, in the midst of a big yawn, "we're going to travel quick on the subway!"
