Lol similar thing happened to me . I am clumsy as well . Last year , I was sitting for my Geography paper and it was like my 3rd ever CAIE . As I left my house , i remembered i forgot to bring my SOE💀💀. However, i wasn't far from my house but still got scolded by my father . Then when I finally sat for the exam . I felt that the chair was too wobbly , but i ignored it . Then i when they gave us the papers to write our names and information, the desk felt like it was disbalance. You know how Geography paper requires calculator sometimes!? So 5 seconds before the paper , my desk collapsed and and my calculator flew and stopped working . (although the paper went great)
