 Dear Linh,

 Thank you very much for the teddy bear you sent me on my birthday. It was nice and lovely. I really love it. I was very happy when I received your present. I'm free now because I finished my mid-semester exam. I want to go somewhere. Would you like to go to Giang Dan waterfall together with me this Sunday morning? I hope you can go with me. I will phone you on Thurday.

 Best wishes.

 Ha.
