26.back to back --------------------------- At noon that day, Jack pretended to sleep under the tree, waiting for Nina to show up. After a while, he heard the sound of someone walking in the grass nearby. The voice kept approaching Jack and slowly came to him. Jack suddenly yelled and jumped. He thought Nina would be scared this time. But Nina pulled down his collar and walked out. What are you doing? Don't do that. said Jack. Follow me. Don't talk. said Nina. Although jack is a little reluctant, he doesn't know what Nina is going to do, but he couldn't help following Nina. Nina takes Jack to the library. She looks for a corner, and she sits jack with his back to herself. Nina sat down too. She put her back on Jack's back and was comfortably ready to rest. Jack finally understood what Nina was going to do. He was angry. Did you think I was a tree or a meadow? He moved a little, Nina hit him on the back with her elbow to keep him still. Can I have a rest, please? Jack didn't move any more... Suddenly, Jack suddenly felt his back lightened. Fortunately, he was quick to respond and pressed his hand on the ground. Jack looks up and he sees Nina's skirt. Do you want to peek at my skirt bottom? said Nina. Jack, turn your head away. Wait for me here at this time tomorrow. said Nina. With that, Nina turns and leaves.
