The wrost thing you can do is have no idea who or what is around you.The more you pay attention, the less likely you are to be surprised. Also, if something does happen and youre a witness, youll be able to provide better information to law enforcement.
The best thing you can do is let others know that you see them and could identify them if need be.When you pass someone on the street, look them in the eye and give a polite nod of the head to acknowledge you see them very clearly.
The only thing thats important is that, at the end of the day, youre the one who lives to see another day You want to make sure you come home every night and get the time you expect and deserve with your family and friends.Thank you.
