Dear Lucy,
I am writing this letter to thank you for your flowers. This is a wonderful gift, and I like them greatly.
I am free recently. If it is convenient for you, I hope you could visit my home. And I want to send a gift for your beautiful flowers.
I am looking forward to you. Give my best wishes to your family!

Yours,
Peng Bochen
