english: AO: You did teach yourself to play, and as a consequence, playing the piano for you, Derek, was a lot of knuckles and karate chops, and even a bit of nose going on in there.
non_english: АО: Ти справді сам навчився грати і, як наслідок, гра на фортепіано, вартувала тобі, Дереку, неймовірних зусиль.
