This is unfortunate because if there was ever a emergency with my family and I was not home I dont think I could rely on them to call the authorities if I need their help.
How would your neighbors know you needed help if you weren't home?
You make friends the same way as when you are young; common interests. By thirty, you've usually decided what your interests will be, removing the majority of potential friends you could have going forward. You also no longer hang out with people your exact age during the majority of the day either.
End result is, you have to do more work that just catching the eye of another person and saying "
Dude! right??" Join communities that share all your interests, not just specific financial ones. Get to know your neighbors - I received lots of first hand information of an audit that took place from a neighbor of a ponzi scammer.
