She entered the sauna with a towel covering her bottom, it's weird that she does this everyday since the sauna was built only for girls, should you ask her a question about it or not, it depends.. she enters the water with a towel still covering her, only then she hid in the hot bath she took off the towel.. she did not speak a word at all and rest quietly.. should you approach her and ask why she is so protective about her own appearance?
