Hello!
I'm Salla and I'm 15 years old girl from Valtimo, Finland. So you live with us next two weeks. My family is very social, and they will talk with you a lot. Our house is quite big, red log house. You sleep in my little sister's room, and she sleep with me. 
We are going to school by mopedcar. School starts at 8.50, so we have to leave 8.30. Our school is quite big for Valtimo, and we have ~200 students. My friends are lovely people, and they talks alot. Breaks are long, and we have one outside-break. After I finish that text, I'll read something about your country.
Finland is quite cold country, so take your jacket. See you soon! -Salla
