Diving is a sport where competitors jump into water from a platform or springboard while performing acrobatic maneuvers. Divers are judged on how well they execute their dives and the amount of splash upon entry. The document then describes how the author's friend Aleksey, who lives near the sea, taught her to dive over two months, having perfect confidence in her ability to succeed. With hard work, the author learned to dive and now teaches her sons and others. She hopes her younger son, who dives professionally and competes, may participate in future World Championships.
