Task 1.Read the email. Then write true or false. Correct the false sentences.

Hi Jason,

I've been trying to phone you, but your mobile isn't on. I didn't want to send you an email, but I need to tell you something before you go on holiday tomorrow.

We haven't been getting on very well for a few months now. I know we've got a lot in common, but I'm not in love with you. I like you very much and you're a brilliant friend. but I don't want to be your girlfriend any more. I hope you aren't furious with me. I've been trying to tell you since we had that argument at Sue's party two weeks ago, but I've never found the right moment. Two days ago you said you wanted to make up, but I think it's too late for me. I'm really sorry.

We've had a good time, but we're still young and I don't want a serious relationship at the

moment. I want to go to university next year and I want to be free to meet new people and make new friends. I hope you can understand this.

Have a good holiday and see you at school in September.

Julie
