School uniform Every day! Who looks cool In Blue and grey? You nave to wear jeans And you shoes are not clean. You nave to be here At eight fifteen.You nave not to wear shorts(I don't know why).You nave not to run in corridors And where's your tie?You nave to tell a teacher If you feel in danger. You nave to ask first Before you go with a stranger.

Заподни пропуски с must и mustn't И ты получишь песню
