I'm OK! This is our first open-water dive. Yesterday we practiced our skills in the pool for several hours, today we put it all together in the ocean. We went out on a dive boat with other divers, but our class stays together as a group. There are the three of us, plus two others: Brian, a PhD Psychology student from Hawaii, and Nadine, a corporate lawyer from Toronto. Since we're leaving on Saturday, the boys and I will take our written test tomorrow morning before the 3rd and 4th open-water dives...
