Dear ....,
Thank you for inviting me to go with you. I'm very excited about it. I have never been there before. I've searched it on the Internet and it's a beautiful place. I really want to visit Cuc Phuong national park with you. We will take a lot of photos together and I will bring some sandwiches for you and me on that day. It would be great!!
Please let me know about the time you can go.
Thank you!
See you later!!
