First off, i want to let u know that my sister started out Modern Orthodox. So she didnt have all the added “pressure” that comes with being more right wing. she had it easy much easier than someone like gitty who started off in a more frum house and in a bais yakov type of environment. She still gave it up. why? she had a roommate,that she assumed was frum, and one shabbos she came home from shul and found her watching tv on shabbos. my sister figured no big deal i didnt turn it on so i’ll watch a little. that encounter led to her turning it on, seeing she wasnt “struck down by lightning” she slowly started doing more things that were michalel shabbos. w/ in a few months she was totally distanced from the life she used to lead.
unfortunately my sister’s spark is very dormant. She has been this way for 17 years ………..
