Then I told one of the kids to call for an ambulance. ,M: Quick thinking. ,F: The girl coughed the water up almost immediately, and just like that, it was over. We cleaned the wound and bandaged it up, and the emergency services arrived 20 minutes later. ,M: How was she? ,F: She had no memory of the past 10 minutes. She wanted to go back in the pool.
