Why doesn't Fayge enjoy the "Sherele" wedding music and dance in The Devil's Arithmetic?

Fayge does not enjoy the "Sherele" wedding song and dance
because the lyrics of the song are negative and pessimistic. She reveals her feelings
about the song when Hannah's friends are dancing by the wagon in which she is riding,
singing,

"Who
asked you to get married?

Who asked you to be buried
alive?

You know that no one forced
you,

You took this madness on
yourself."

Fayge tells
Hannah,

"I
always hated the 'Sherele'...such a gloomy song for so glorious an
event."

Fayge is right in
that the song lyrics do seem innapropriate for a joyful occasion like a wedding; it is
ironic that the song should be considered a wedding song. The young people sing and
dance to it unthinkingly, however, probably not even aware of the foreboding sense of
the words. Apparently, the "Sherele" is like many singing games played by little
children, such as "London Bridge Is Falling Down". While the original meaning of the
words may have ominous connotations, no one pays much attention to them; the music and
dance have become such a part of tradition that the implications of the lyrics are not
even thought of anymore.

In the context of the book, the
singing and dancing of the Sherele serves the function of foreshadowing. The dark,
negative tone set by the lyrics are fulfilled just a few minutes later, when the wedding
party is accosted by the Nazis (Chapter 8).
