Forgetful Nick
After school on Friday, when Nick got home, he saw Grandpa's car! Nick smiled and walked quickly up the front sidewalk.
He reached the door and said hello to Grandpa. Then Mom called from the kitchen. "Put away your schoolbag first."
Nick's smile vanished(消失). "Oh, no," he said, "I forgot to bring my schoolbag home."
Mom was angry. "Nick, you forgot your schoolbag again! You need to be more careful!"
Grandpa turned to Nick and winked(眨眼), "I'm afraid you inherited(遗传) your forgetfulness from me, Nick. Your grandma used to call me 'Forgetful Jones'."
Grandpa's words made Nick feel a little better. But he still felt mad at himself.
After dinner, Grandpa suggested going for a walk. As they walked around the corner, Grandpa said, "I'll tell you a little secret, Nick. We're the same. We like to do things, make things and have fun! That's why we sometimes forget things."
"But Grandpa, how did you stop forgetting? How can I stop forgetting?" Nick asked.
"Well," said Grandpa, "I know a few tricks(窍门). I use them to help me remember important things. For example, it's important to turn off my car lights when I park the car. So every time I get in the car, I put my notebook in my lap(大腿)."
"I saw it!" said Nick. "I always wondered why you did that!"
"Now you know my secret," said Grandpa, "It's a simple little trick, but it works. Why don't we put our heads together and come up with a schoolbag-remembering trick?"
