They’ll notify you of neighborhood crime
When the neighbors know each other, you can all keep each other up to date on neighborhood crime. This is especially important information for a woman living alone to have. If there is a man, for example, who has been following people to their car at night, women living alone should know that. Maybe find a neighbor to walk with you to your car at night. That’s just one of many things women living alone can do to improve their safety.
