Переведите на русский
Olga wrote that she was enjoying her seaside holiday very much. She said that she had arrived in Ireland a week before and had been spending every day swimming and having fun. She added that when she was writing that postcard, she was waiting for another hotel guest so that they could go water-skiing together. Olga said that she was also going to try scuba diving and she was even thinking of doing some underwater fishing. She also added that she had been very busy and she had not given herself any time to just lie on the beach and sunbath, but holidays were about having fun. She said that she would tell Anna everything when she got back.
