The fuller answer
Foster care is a system arrangement, not an identity or verdict about a young person. Placement can bring safety and also loss of home, routines, school, privacy, belongings, siblings, pets, and contact with people who matter.
A young person may feel relieved, furious, loyal to birth family, attached to foster family, numb, or unwilling to trust. They do not have to perform gratitude or instant attachment.
Young people in care have rights that vary by location, often including education, health care, case information, contact with siblings or family when safe, personal belongings, privacy, and a way to raise concerns. A caseworker or advocate should explain local rights clearly.
