On weekends many Russian people simply spend time at home: they watch TV, read books or do housework that has accumulated during the week. Young people play computer games, communicate in social media or just “surf” the Internet. Some women are fond of handcrafts: knitting, sewing and making designer jewellery – for themselves or for sale. Parents try to spend more time with their children. Russian people have personal, more specific hobbies like car tuning, taking photos, or war-historical reconstruction. Usually there are special thematic websites and message boards dedicated to these hobbies and their subscribers regularly meet offline. At such meeting good communities are formed where people can find new friends or even a new love.
