Final answer:
The aggressive child should say 'I'm sorry for hurting you' to the victim, as this shows remorse and acknowledges the emotional harm or physical harm caused.
Step-by-step explanation:
When a child has hurt another child, either physically or emotionally, the appropriate action is for the aggressive child to apologize sincerely. The correct statement to make is 'I'm sorry for hurting you.' This acknowledges responsibility and shows remorse for their actions, whether it involves emotional harm or physical harm. It's essential for children to understand the impact of their actions on others, and apologizing helps to mend relationships and to start repairing any damage caused. Statements such as 'I didn't mean it,' 'You deserved it,' or 'It was just a joke' can undermine the severity of the situation and fail to validate the feelings of the child who was hurt.
