    Dear Prof. Wang,
    
    First of all, please allow me to express my deep sorry for not being able to keep our
    
    appointment. I do know that this is very impolite and must have caused you much trouble.
    
    I do reckon that at present any explanation is pale and futile. However I do not want you to misunderstand me. On my way to your office, an old lady suddenly fainted due to heart attack on the bus. I stopped a taxi and sent her into a nearby hospital. I stayed there until her son came, which spoiled our appointment.
    
    I am aware that our appointment is of importance. I do hope that you would be kind
    
    enough to spare your valuable time to meet me.
    
    I am looking forward to hearing from you.
    
    Sincerely yours,
    
    Li Ming
