Dear ………………. ……………….,
Hi! This is Daniel, your pen pal from United States. Hope you are fine and well; I am writing you because this summer I will have the chance to travel through Europe. As you know, I am deeply fascinated by art history, and lately I have been listening to a radio show where they talked about something called Expressionism. I am really eager to know something more about it. As I heard, it is a kind of art movement, but I did not really catch where the movement spread, who the main artists were and the technical features of the paintings those artists realized. 
Can you help me? Looking forward to see you soon.
Daniel
