У математиці є спеціальне позначення для прямих, які перетинаються під прямим кутом. Такі прямі називають перпендикулярними. Позначають символом: a⟂b (a перпендикулярна b).ми говорили про прямі, які перетинаються. Але буває ж так, що прямі не перетинаються. З цим ми стикаємося і в житті – у лижників під час спуску права лижня і ліва не перетинаються; або доріжки в басейні – вони також не перетинаються; або залізнична колія – рейки не перетинаються. Для непересічних прямих також є спеціальна назва.

The next morning, Gillian flew around Thistleberry Glen. She saw Carly, Siobhan, Rabbie and Harry standing talking. She flew down and landed next to them. "What’s going on here?" she asked.

Carly mooed, "In the middle of the night, someone delivered a package of sweets to each of us. We don’t know who it was!"

Gillian smiled. "I know who it was!"

Siobhan went baa. "Tell us. Who would do such a nice thing? I’ve never tasted such delicious tablet, shortbread and pastries before."

"It was Fraser, the big purple dragon that lives in the cave. I saw him myself," Gillian answered.

"Fraser? That clumsy dragon?" Harry squealed.

"Surely you’re mistaken," Rabbie added.

"No, I saw him. He left me a package too. I think we should do something nice for him. I imagine he must get chilly in that damp cave," the grouse said.

"I’ve got a splendid idea," Siobhan said. "Let’s use my wool. It’s nice and thick and warm, and we’ll make him a blanket. You can all knit, can’t you?" she asked the others.

They all nodded. They spent the day plucking wool from Siobhan’s back and knitting. When they were done, they sewed each strip together. "That’s lovely," Carly said, looking at the finished blanket. "It will keep him warm all winter long."

Rabbie wrapped it in some beautiful silver and gold paper. Harry tied a golden ribbon around it. "Let’s get him a tree too," Harry said. "I’ll make the decorations if you’ll find the tree."

Carly and Siobhan found a wee pine tree. Harry and Rabbie hung nuts and rowan berries on it. Gillian used some of her feathers to decorate it. "That’s lovely," she said as the finishing touches were added. On Christmas Eve, after the sun went down, the five animals carried the tree and the wrapped blanket and set them down outside of Fraser’s cave.

Christmas morning came around. Fraser was feeling rather sad. His fingers were cold and his claws were almost frozen like icicles. His horns had frost on them and he couldn’t feel his tail, which had been lying on the ground. He stood up and rubbed his arms and went outside. "What’s this?" he gasped. He picked up the package. "It’s a Christmas present," he laughed. He opened it up. "Oh, a lovely woolen blanket. Who made this?" he wondered. He looked at the tree. "Rowan berries, nuts and feathers. How pretty! It’s the best Christmas tree I’ve ever had!"

He went back inside and turned on his oven and started to make himself a Christmas meal. As he was chopping the leeks, he heard a noise coming from the entrance to his cave. "Can we come in?" Carly asked.

Fraser was surprised. He had guests on Christmas Day! "Come in, all of you. I’m about to fix supper. Would you like to stay?" he asked.

Carly, Siobhan, Rabbie, Harry and Gillian spent the rest of the day in the cave with Fraser, nibbling on his leeks and potatoes, haggis, sausages, bacon, sweets of every sort imaginable, bannocks, raisins and boiled eggs. "This is the best Christmas I’ve ever had," he sighed, happily. "Thank you for the blanket. There’ll be no more cold nights for me now." He noticed that Siobhan didn’t have as much wool as usual and smiled at her. "Merry Christmas to you all," he shouted.

"Merry Christmas to you too, Fraser," they replied.

From then on, the other animals in Thistleberry Glen stopped by Fraser’s cave for tea and caramel shortbread whenever they were nearby and even invited the dragon to their houses, even though he was too big to fit inside.
