By the way, author doesn't describe what is Valerie's school like. Is it big or small, how many storey, what about space around? When I read, it is clear in my mind. I imagine that it's three-storey building in brown-brick style. Around the school there are a lot of space with green grass and trees. May be it's smth like this:
Valerie and other pupils go to school by bus. Of course I conceive that yellow bus, which we always see in different films.
What about house where Valerie lives? I think it's not big, but without a doubt it's two-storey building.
Under the window of Valerie's room there is a big tree, I think it's maple.
And what clothers she likes to wear? In that time it's nor important for her, she doesn't care about her appearance at all, but I imagine that she wears checkered skirt and blouse, everything in light warm coloures.
