The Demonstration

"Guess what?" Grace bounded into the kitchen, followed by her friend Ava. "Ava and I volunteered to give a demonstration at the next youth club meeting.""That's great," said Mom. "What will you demonstrate?"Both girls looked at her with a blank stare, and then burst into peals of laughter. "We didn't even think about that," said Ava. "It just sounded like fun to get up and give a demonstration!" All was quiet for a moment. Then Ava snapped her fingers. "I know. Let's give a demonstration on flower arranging. My mom has a book that shows how to do it. I'm sure she'll let us use it.""Good idea," said Grace, so the girls went to Ava's house and spent the afternoon studying pictures and instructions and practicing arranging flowers.Finally, they returned to Grace's house to show her mom a bouquet they had made. "This is the kind of arrangement we plan to demonstrate," said Ava."Beautiful!" Mom exclaimed. "That's really lovely.""We have three weeks to practice and get our speech ready," sai
