Dear Rose
Thanks for coming to my birthday and you are so kind to give me the MP4 for my birthday present. I love it so much that I listen to music when I am free. I long for it for a long time. But it cost so much that I don't buy one. I am sure you spent a few weeks pocket money on it. This is the best birthday present I received. Thanks for your generosity and your kindness again.
Yours: Mary
