The poet Sergei Gandlevsky, who knew Rubinstein well, called him “implausibly sociable.” Rubinstein was choosy with his company, but was generally very friendly, sociable and accepting of many invitations. However, his career came to a halt when he lost his job after Putin’s rise to power. Rubinstein wrote a letter to Boris Akunin in which he shared a negative view about present-day Russia. Despite some readers leaving, any latest poem Rubinstein shared was highly morose. After mulling over emigration, Rubinstein opted to remain in Russia; he continued with writing and was active on Facebook. Shortly after a dreadful poem on Facebook, Rubinstein was hit by a car on the way to the post office and after being hospitalized, he succumbed to his injuries.
