Instructions from the Girl's Parents
The girl's parents instructed her to always walk home with a friend or a group of friends. This is a safety measure to ensure that she is not alone and vulnerable to any potential dangers she may encounter on her way home.

Reasoning Behind the Instructions
Walking home with a friend or a group of friends provides safety in numbers. In case of any unforeseen circumstances such as encountering a stranger or facing a dangerous situation, having companions around can help protect the girl and provide support in handling the situation.
Additionally, walking alone can make someone an easy target for potential threats like abduction, harassment, or robbery. By following her parents' advice and walking with friends, the girl can reduce the risk of becoming a target for such dangers.
Moreover, walking with friends can also make the journey home more enjoyable and social. It allows for conversation, laughter, and shared experiences, making the walk a pleasant and bonding time with friends.
In conclusion, the girl's parents gave her the instruction to walk home with a friend or a group of friends to prioritize her safety and well-being. By following this advice, the girl can feel more secure, protected, and supported during her journey home.
