Adam , I'm sorry !   But where have you been , Alice ? You're over an hour late .   Yes , but I couldn't help it . I was late getting off work for a start , and then I missed the bus . The bus I did catch got caught in a traffic jam . It was one thing after another .   But why were you getting off work so late ? The office close at six , doesn't it ?   Yes , but there's a rush on at the moment , and my boss asked me to do some urgent letters .
