Whilst wandering around Walgreens last night, we spotted this and both assumed somebody had made a huge spelling error and put 'Bat' instead of 'Bar'! We were tickled enough we took this piccie as neither of us, despite being pretty knowledgable, have ever heard the term 'Bat Mitzvah'.
Well we got home and 'googled' as you do and lo and behold it's correct! This is the term for a Jewish girl coming of age at 12yrs, as opposed to a boy who is a 'Bar Mitzvah'.
You really do learn something everyday!
