"You are a wizard."
Translation:Sinä olet velho.
These are important things in Finnish culture. We are learning about the culture as well as the language. Imagine learning about UK culture and no one ever mentions any Shakespeare character/piece, the iconic high-hat guards, Elizabeth's Tower, kilts and bagpipes, Stonehenge, druids, Doctor Who...
I may have overdone it with a few examples; I'm not from the UK myself. I just chose it because I know the best about it from all the other countries.
