It was a beautiful Caribbean day, water conditions were excellent but Anna was feeling confused. Water had started to seep into her mask and, although she knew how to clear it, somehow she was unable to get the water out. She started to ascend.
Concerned, the divemaster followed her up, signaling to Pauline, the other diver in his charge, that she should wait and he would come back. On the surface, Anna removed her regulator, adjusted her mask, gathered her thoughts and decided she had been foolish.
