Dear Aldy, Long time no see, how are you today? I hope you are alright Last holiday, my family and I spent one night in the countryside. It is not far from our city and it is not a crowded place. We stayed in a rented wooden house. It was really nice. At night, we made a small fire in front of the house and sang together. We were very happy. We woke up very late the next morning because we stayed up till after midnight. After lunch, my father drove us home. It was a great holiday. Will you join us next time? See you soon Your best friend, Sandy "Will you join us next time?" What does the word "us" in the sentence refer to?

Dear Aldy,

Long time no see, how are you today? I hope you are alright

Last holiday, my family and I spent one night in the countryside. It is not far from our city and it is not a crowded place. We stayed in a rented wooden house. It was really nice.

At night, we made a small fire in front of the house and sang together. We were very happy. We woke up very late the next morning because we stayed up till after midnight. After lunch, my father drove us home.

It was a great holiday. Will you join us next time?

See you soon

Your best friend,

Sandy
