My first language is Dutch, but in Holland it's normal to speak English, and German/French as well. I am also learning Spanish.
I started with English class at school when I was like 10? But at that age I could speak English already a bit.
And I still have English, am now 15, and I will have three more years English before I graduate. And then also exams for French and Spanish. I always hated German
For a small country as the Netherlands, it's just normal to speak two or three languages.
