I think that life outside of school as an adult will be much more important than being a student. I think that because as a kid you are protected from most things, and are also forgiven for most things you do. This is different from when you are an adult. As an adult you are taken more seriously, and have more responsibilities than a child. Hope this helps!
When walking around at night, it is safer to walk with another person or in a group.
If you feel like you are being followed, try to go to a public place with other people.
If you see something suspicious, distance yourself from the scene before alerting the authorities.
Be realistic when dressing & choosing accessories or jewelry before traveling on the streets at night.
Hope those help.
