Secondary school teacher passed away

Today when I first step into office, a friend of mine who happened to be in the same secondary school as I was told me a bad news. Our secondary school teacher, Mr Wong Kiow, has just passed away. I was quite shocked as he is only 62 and I have seen him about a year ago. He looks very healthy to me though I dunno what causes his departure. He taught me Maths when I was in Secondary 2. He looks fierce but he is quite a good teacher. Farewell Mr Wong.
