The Bovington signal course's director reported that Gaddafi successfully overcame problems learning English, displaying a firm command of voice procedure. Noting that Gaddafi's favourite hobbies were reading and playing football, he thought him an "amusing officer, always cheerful, hard-working, and conscientious." Gaddafi disliked England, claiming British Army officers racially insulted him and finding it difficult adjusting to the country's culture; asserting his Arab identity in London, he walked around Piccadilly wearing traditional Libyan robes. He later related that while he travelled to England believing it more advanced than Libya, he returned home "more confident and proud of our values, ideals and social character."
