Translation of Briefpapier

I will put that one and the offending words. These words should not be optional, cause we need to know when a word is offending. Would it be helpful to have a counter, so you see how many words you translated?
I was born in 1967 in Zurich, Switzerland. It is a small city, but not as small as Basel or Geneva. I grew up in a suburb of Zurich. When I was 12, I moved with my parents to Spain.
Since when have you been learning Spanish? My children are not on Vocabulix, they are too small for it. We have no time for the normal day activities, and we are always on the move with the children.
