Dear ____(name)___,

I wrote this to say thank you for the birthday present and how grateful i am. I opened your present and saw the encyclopedia you sent me. Again, thank you very much!!

The encyclopedia is very interesting and useful. The illustration is very beautiful and meticulous. I love it! I will regard and keep the book clean and safe!! Thank you very much, again!

I wonder what everyone will give me in my next birthday. I want a new pair of shoes for my next birthday. Talking about birthday, i can see that your birthday is coming near. What about you? What do you want for your next birthday? 

I think i'll have to end the message here, i have to study now. Thank you very much for the encyclopedia, and remember to reply soon.

Best regard
