It was after lunch and Mr.Sonic's class was heading back to his classroom to get their belongings. A boy named Jack was running up to the school wall and was jumping on it, trying to walk on it. He was doing this for a long time while Maddie and I just watched from behind . Mr.Sonic was in front of us and the moment there was no more walls for Jack to jump on, he turned to him and asked him in a very loud voice "WHAT ARE YOU DOING?!" Maddie and I stopped and covered our mouths wit our hands to try to not laugh. Jack just looked at Mr.Sonic for a while before going in front of him and just walked to class.
