Btw, do no be afraid to tell your kids that what they saw/heard someone do is not allowed for a Jewish girl/boy. They SHOULD know that what was done is against halacha or not in line with a Torah lifesyle, however, it is not their place to judge somebody else’s level of halacha/hashkafa. Their job is to work on their own Yiddishkeit.
(But call it what it is. If it’s assur, then it’s assur. If it’s a chumrah, then call it that….)
