I’ve wondered for a long time if Rachel and her family were lapsed Jews. Green could easily be short for Greenberg, Greenbaum, or Greenspan. Sure, she celebrates Christmas but so do Ross and Monica who we know are Jewish. But, just now, Rachel was describing her grandmother
‘Has no sense of personal space, looks like a potato’
“Spuds is your grandmother?”
“Yes! That’s my bubby!”
Bubby is the Yiddish word for grandmother. I consider this final proof that Rachel is Jewish. This, of course, makes Emma Jewish as well.
The question has bugged me for years, and I’m glad to finally have an answer.
