Dear Dr Xi,

what a lucky forum this is to have the services of a resident physician such as yourself so expert in matters pertaining to psychiatry, and able to diagnose so precisely such a severe neurological condition as has apparently afflicted our friend Mr M.

i have been led to believe that china in fact leads the world in this area, and has a wonderful network of depression - counselling centres for people just such as him and others like him, all of whom suffer from neuroses of the "the-world-is-not-flat" variety. perhaps you could recommend him for admission to one in his area?

yours hypocratically,

Miss Tick.
