"Maar wauw, wat heb ik daarnaar uitgezien." --> "But wow, how I have looked forward to that"
"Hoe anders was mijn leven tot nu toe" --> "How different was my life up until now"
"Elsa: Alleen omdat dat hoort. / Anna: Dit is zoals het hoort!" --> "Elsa: Just because it's supposed to / Anna: This is how it's supposed to be"
