We always stayed in accommodation close to the shore because my parents had a good relationship with the owner of the hotel. We also went snorkelling each time and 【would】 dive under the waves to see the colorful fish. As I grew older I was allowed to go to greater depths and further out beyond the bay. There I saw small sharks as they swam lazily around the sea bottom. One day I witnessed how they 【would】 pursue their prey swiftly, and the small fish had no time to flee away.
