We had other interests in common apart from mathematics: Freundlich was a keen cellist, and we frequently played chamber music where I played the violin or viola.
Kami ay may iba pang mga interes sa mga karaniwang bukod sa matematika: Freundlich ay isang masigasig byolonselista, at madalas namin nilalaro ng kamara ng musika na kung saan maririnig ko ang violin o byola.
