He was shy and very self-critical. He hated having to talk to people he did not know. He did not sit still, always fidgeting and twitching his face nervously. He was, however, always very polite and very kind to everyone he met. An obsessive for cleanliness and timekeeping. Nervous, fidgety, facial ticks and grimaces. Shy and diffident and unable to say 'no'. Despite the brooding typical of so much of his music, which might suggest an introverted personality.
