skateboarding is a hobby of mine.
[{"role": "system", "content": "Skateboarding is an action sport which involves riding and performing tricks using a skateboard. Skateboarding can also be considered a recreational activity, an art form, a job, or a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding will be represented at the 2020 Olympic Games in Tokyo, Japan. Since the 1970s, skateparks have been constructed specifically for use by skateboarders, Freestyle BMXers, aggressive skaters, and very recently, scooters. However, skateboarding has become controversial in areas in which the activity, although illegal, has damaged curbs, stoneworks, steps, benches, plazas and parks. The first skateboards started with wooden boxes, or boards, with roller skate wheels attached to the bottom. Crate scooters preceded skateboards, having a wooden crate attached to the nose (front of the board), which formed rudimentary handlebars. The boxes turned into planks, similar to the skateboard decks of today.\n"}, {"role": "assistant", "content": "do you like skateboarding? it can be a job, method of movement or recreational activity"}, {"role": "user", "content": "I've tried it once, but I was not very good.
