Miro is normally very likable and funny.

I remember one prominent Finnish go player having had a tendency to lose it over a lost game of billiards. He never broke any stuff or caused any harm to anybody but would pace around and fulminate for a while in a way uncharacteristic of a mature adult. That was about 20 years ago. He was in his mid-thirties at the time. He had and still has many traits that I believe are indicators of Asperger's syndrome.
