Avery So I just object when someone like @curious says some girl he doesn't even know must wear a belt even if she's a Muslim.
I am not saying she must.
If Amira is OK with your way of handling things, where she just tries her best but if she fails her goals, she just continues, then she can take your approach as example. But if even one failure to follow her rules is completely unacceptable to her and that is her priority, what is wrong with going for strict 24/7 wearing?
First you define your goals. Then you look at how to achieve these goals and what sacrifices you are prepared to make for reaching these goals.
If Amira decides for herself that in order to ensure her hymen is guaranteed intact she is prepared to live 24/7 in thigh bands and the benefits outweigh the restrictions in her very personal weighing of things, we should accept her priorities rather than telling her to follow someone else's values instead of her own.
