【明報專訊】MoMo misses her friend Susan, who lives abroad. She has written her a letter. When one writes to one's friend, one uses an informal style. An informal letter's wording is different from a formal letter's. It is easier to say in a letter what one finds it hard to say to another's face. And it is good to keep in touch with friends who live in faraway places by writing to them.

Dear Susan,

How are you doing? I can't believe it has already been a year since we met last. How are you lately? Do you still go kayaking every week?

I miss the time we were kayaking around Rainbow Island. I have met new friends at the kayaking club in my hometown. I hope you still enjoy the sport, and I can't wait to see you again.

Love,

MoMo

opening sentences in informal letters

The opening sentence of an informal letter is different from that of a business letter. It should be casual rather than formal. Examples are ''I hope you are doing well.'' and ''How's life treating you?''
