   When I was in hospital last year, I looked forward to visiting times. I was cheered up by visitors who talked and joked with me. My teacher knew how boring it was to be alone. She brought me a game set on one of her visits. Some of my classmates gave me fruit and flowers when they visited me. Andi sent me a get well card. He could not visit me because he was also ill. I am lucky to have caring friends.
