mr and mrs davis have a son. his name is bobby, and it was his birthday a few days ago.

last sunday bobby's grandfather came to visit them, and he brought bobby a nice toy train. when he gave it to bobby, he said: "i'm sorry, bobby, but i forgot your birthday last tuesday, so i give you this present then."

"oh, that doesn't matter grandpa," bobby answered. "thank you very much. it's just what i wanted."

"and how old are you now, bobby? " his grandfather asked. bobby knew the answer to that question. "i'm five, grandpa," he said.

"that's good," the old man said. "you're a big boy now, bobby. and what are you going to be when you're older? " bobby knew the answer to that question, too. "i' m going to be six, grandpa," he answered  этот?
