An invitation letter

Q: What are we going to do?

Dear Sam,

I'm writing to invite you to our party. We are going to have a party on the night before the Spring Festival. Would you like to come and join us? We will be very glad if you can come. The party will start at 6:00. I will wait for you at the school gate. I think the party will last for three hours.

It will be very cold at night. Please wear more clothes.

Yours sincerely,

Amy
