My daughter told me that some girls in her Beis Yaakov Seminar did not fast on the Fast Of Gedaliah. I told her that as far as I know they are required to fast, unless they are pregnant or nursing. Of course, nobody in her 10th grade class fits that description. She wanted proof so I showed her the appropriate chapter in the Shulchan Aruch.
Is there anyone out there that can explain why some women do not fast?
