The class was learning how to express ability using “can” and “can’t”. He challenged the students to say AND show what they can and can’t do. Mark surprised his students by showing him that he can put both of his feet behind his head. He is really flexible!
All of the students were truly amazed, started laughing, and many of them got their cameras out to take pictures of their teacher in a funny position on the floor. Mark may have looked strange during that lesson, but I don’t think the students will forget the difference between “can” and “can’t” now!
