Dear Sarah, What is it like there? Still snowy? The weather is still hot here, just as hot as when you came
here to join the international arts festival a month ago. About your invitation to come to visit you, I am
not sure if I can go there. In fact, it's nearly impossible because I don't think I can afford it. So, why don't
you come here? I'll show you around my beloved hometown.
Love,
Lia
