slips of the tongue

Yiddish in common English

Sometimes I hear them

Sometimes the wall between this world and the Other World is as thin as the walls of an East Side tenement; one can hear the dead carrying on in Yiddish, playing accordions, cracking jokes. One can hear cantors davening, vaudevillians doing shtick as if in mountain casinos.
