A sandwich novel is a form of literary work. It often consists of different narrative layers. The 'filling' part is the core of the story, around which there are other elements that add depth and complexity. It's like a sandwich where the main ingredient is the focus, but the bread and other toppings enhance the overall taste. In a sandwich novel, the outer 'layers' might introduce characters or situations that lead into the main story and also tie up loose ends after the main plot has been told.
There was a girl who had a brand - new dress with a long zipper at the back. She was getting ready for a party. When she was about to zip it up, the zipper just wouldn't budge. She called her sister for help. Her sister tugged at it a bit too hard and the zipper came off completely. Instead of getting upset, they found it hilarious and the girl ended up wearing a different dress to the party and told everyone the funny zipper story.
Imagine a circus clown. His pants had a huge, colorful zipper. During his act, he pretended that the zipper was a magic entrance. He tried to 'open' it to pull out a bunch of handkerchiefs, but instead, the zipper got stuck. He struggled and made funny faces while trying to fix it, which made the whole audience burst into laughter. It was a total mess but also extremely funny.
Once upon a time, there was a strange dog with a zipper on its back. One night, a little girl heard scratching at her window. She peeked out and saw the zipper dog. Its eyes glowed red in the dark. She was so scared that she hid under her bed. The dog then started to unzip itself, making a horrible zipping sound. After that, she never saw the dog again, but she always had nightmares about it.
The sandwich is said to have originated from John Montagu, the 4th Earl of Sandwich. He was a gambler who didn't want to leave the gaming table to have a meal. So, he asked his servants to put meat between two slices of bread. This convenient way of eating soon became popular and was named after him.
