People who abuse children often first build a relationship with the child. Many sexual offenders are good at making friends with children and those who are close to them. Some may befriend a parent who is facing difficulties. They may offer to babysit or help with childcare and other responsibilities. Some may work in places that put them in close contact with children, such as childcare facilities, schools, children's groups and sports teams. Some spend time in places where they get to know children, e.g. arcades, playgrounds, parks, swimming pools and around schools, and so are not seen as dangerous strangers.
