Subject: Give me some advice

Dear Katherine,

    I have a problem with my best friend. I like playing with my mobile phone till late night and I often sleep in class. My best friend advised me not to be like this, but I refused to listen to him. So we get separated day by day.

    What should I do? Shall I say sorry to him? How can I keep our friendship? Can you give me some advice?

    I am looking forward to your letter.

Yours,

Betty
