And what went through my mind was, how often is it that teachers are thanked by their students for teaching them variables?  It doesn't happen in most classrooms, but that's because in most classrooms, when kids learn about variables, they don't know why they're learning it.
Ik vroeg me af hoe vaak leraren door hun studenten worden bedankt als ze hen variabelen leren gebruiken?  Niet vaak, omdat kinderen er het nut niet van inzien.
