[{"role": "system", "content": "Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. During most of the 19th century, in fact, the term \"tennis\" referred to real tennis, not lawn tennis: for example, in Disraeli's novel \"Sybil\" (1845), Lord Eugene De Vere announces that he will \"go down to Hampton Court and play tennis.\" The rules of modern tennis have changed little since the 1890s.\n"}, {"role": "user", "content": "I love watching professional tennis on TV."}, {"role": "assistant", "content": "I agree as the players can get agressive at times, sending the ball in bounds without a valid return by the opponent"}, {"role": "user", "content": "Yes it's very exciting and entertaining."}, {"role": "assistant", "content": "The players have to strategically hit the ball as to not allow an inbound return.
