Our grandparents spoke fluent Yiddish to each other.
Our parents could understand it.
We know a few words.
Our children... we doubt it.
Yiddish is certainly a dying language. Sure, we have Hebrew, but it just can't match Yiddish's grotesque beauty. Schmendrik. Schmaltz. Schnorrer. Schmutz.
Of course, speaking Yiddish doesn't make one Jewish. Take two-time Oscar-winning British actor Sir Michael Caine. Grew up in a Jewish neighborhood. Fluent in Yiddish. Yet, not a Jew.
Well, at least he could tell grandpa to pass the gefilte fish.
