Haha it was the only language that was taught in my small village elementary school back in 1998 in 3rd grade. Then I went to high school in 2001 and my parents figured (rightly so) it wouldnt make sense to throw away what I learned in the previous years, and started with English several years later.
It got surprisingly useful when I landed my first job in 2014, I never aimed to get to a German company but I accidentally ended up with REWE, and went for several trips to Vienna + there were corporate guys coming over from Cologne so it got quite handy. Now I havent been using it for 2 - 3 years at work again but its always fun to go out to Austria or Germany and understand majority of stuff on the streets etc
