Please, correct my English mistakes, thanks.
last sunday I went to the beach in the afternoon, It was a very good experience, I went with my mother, my brothers and my nephew. We catched a bus at about 2:30 pm, we thought it was already late, but it was still early,actually. When we arrived in the beach, it was a bit cold, at least I felt that, it was a bit cloudy, but we jumped into the cold water. The waves seemed very dangerous, there was a red flag which was a sign that the sea was brave. In fact, the waves came very high, turbulent and swirling. In despite of that situation we kept swimming and enjoying the potentially dangerous waves, and we did not care about anything. We got scared when a man was about to drown because he went deeply into the dangerous waves of the sea, fortunately there were life guards who realized and at once jumped into the sea to save the poor man. After that, we were more careful, but we kept in the water. Then, we played soccer for a while until it was dusk. Finally, we went back home very tired. It was definitely a day to remember.
