Dear George
How's it going?I'm going to fly to The US next week.As you are my best friend,I really hope I can meet you then.
I'm going to stay there for three days.Of course,if you are available,you can have fun with me .The first day we will go to the shopping centre to buy some shoes and ties.After shopping,we will go to the KFC for eating.
The next day will be mainly to study.I hope you can teach me some Engish and some culture in you country.It will be very interesting.
The last day will be the happiest day.We will go to the beach,swimming,going to a picnic there.After that,I have got to go.
I think we will enjoy ourselves,I'll telephone you as soon as I arrive.
