Dina had grown up in a family of divers. Almost every weekend the family gathered it's gear and set off for one diving spot or another. Now it was Din's turn to learn. she had been nervous at first. the air thanks had seemed heavy and bulky. the mask felt tight on her face. soon,however,she had passed through all her training. this first dive had been wonderful. the sea and its creatures had been all around her. hey, she called to her brother up in the boat. can this fish come aboard?
