DD has a friend who is half European and half Syrian. Friend's mum converted to Islam before marriage. Initially, it was not obvious they were practicing Muslims. No talking about it, no hijab, liberal (alcohol in house), among other things, until recently. Recently, the pre-teen friend fasted with her family for Ramadan, mum has just started wearing a hijab in the last fortnight and dad has forbidden friend to visit anyone's house without mum accompanying for the whole visit.
My question is, if the family is becoming more devout, about which I have no problem with, how common is it for 11 year old girls to need constant supervision when not at home or at school?
