Henry: Hi, Alice. You look unhappy. What's the matter?

Alice: I had a fight with my best friend, Helen. Now I know I'm wrong. ?

Henry: You should say you're sorry to her.

Alice: I know I should, it's hard to speak out and I feel shy to see her.

Henry: write an e-mail? She often surfs the Internet and she will see it.

Alice: I don't like writing e-mails.

Henry: Oh, you could send her a text message on your mobile phone.

Alice: But of us have a mobile phone.

Henry: Well, I remember it's her birthday next Sunday. You could go to her party.

Alice: I'll buy her a present. It will surprise her, I think.

Henry: I'm sure she will like your present and you will be good friends again.

Alice: Thank you for your advice.

Henry: You are welcome.
