Our first day hunting for seashells and conches involved major teamwork. Since neither of us can swim or dive, we resorted to holding each other’s arms while the other grabbed shells from under the water with their feet. My sister died of laughter when, excitedly, I exclaimed to the world that I’d found a conch, only to realize that it was a big rock. Biggest fail. We had a day of intense laughter, that’s for sure.
