Son is playing Macbeth in the Guildhall tomorrow night as part of the 'Shakespere in schools' project. He doesn't have an understudy. He sounded like the Kurgan from Highlander on Sunday night and felt a bif 'urgh'. He went to school and rehersals yesterday and he seemed better. He's just been sent home from school, dripping snot, bleary eyed and the glands in his neck are very swollen. He's crawled into bed. I've put the central heating on, given him paracetemol, Vit C and told him to drink lots. Any other bright ideas?
