I’ve been learning Finnish for nearly a year. The first phrase it taught me was “Sinä olet velho”. I thought it was madness to teach me “You are a wizard”. Like, when am I ever going to use that?!
Later that year, I was performing at a forest festival in Finland, and a guy staggered past wearing a wizard hat. The way his face lit up when I yelled “Sinä olet velho!” was priceless!
