The document summarizes observations of a 6-year-old child's behavior in different social situations. When with adults other than parents, the child is shy but lively and outgoing with friends. The child's behavior changes around toddlers, becoming more careful. When asked why they act differently, the child exaggeratedly explained that adults are "big and scary" while babies are "cute." The child's favorite activity is tackling people to show affection. Communicating mainly through gestures at this age, the child is developing language skills. Psychological studies are limited as each child's development depends on their unique environment and interactions.
