When the oldest daughter turned thirteen the family planed a trip to Palestine to visit the grandparents. When I asked her if she would be wearing a burka while on vacation she replied, "of course not, I'm an American and we don't have to that". When they returned from the one month vacation she was wearing a burka. And she has worn one in public ever since. The kids at public school tease her quite a bit and it bothers her so I have not mentioned it.
However, I can't help but notice that she has changed.
The Palestinian girl has most probably changed because maybe she was abused via the practice of female circumcision.
