Katyusha has a full intellect, she is sociable, cheerful, loves to make new friends and absolutely adores singing. Together with her mum, she visits the Dubossary rehabilitation center for children with lifelong learning. The family later moved from their little village to the city nearby to be able to attend the center on a daily basis. Katya really likes it there. Among the procedures Katyusha requires are special massages and gymnastics. Katya also receives general education. All her life Katya has not yet visited any other place, so she is really excited to spend some time with her mum, swimming and sunbathing by the sea.
