Teen girls in Australia have been warned about drawing their phone numbers on their backs while sunbathing in order to meet boys. A group of Sydneysiders between the ages of 14 and 15 got national attention when they were photographed by a local paper with their numbers painted in zinc cream on their lower backs. The local police commander says the behavior is "risky" and "inviting trouble," while a campaigner for young women calls the behavior "trashy." [Daily Mail]
