Most people are about themselves, self preservation, and what suits their best interests in the long and short term.
You'll save yourself a lot of headache when you realize that outside of your immediate family (mother, father, brother, or sister) that most people are not going to have your back when life starts getting hectic.
A lot of people throw the word friend around to loosely.
You'll do good if you make 3 good friends in a lifetime. When I say friend I'm talking about someone whose house you can go sleep when you don't have anywhere else to go, someone who will buy you food when you are broke and hungry, someone who will help you get a job when you're jobless, someone whose going to come through and put money on your books or post your bail when you locked up, someone whose going to come fight beside you known both of y'all about to take an azz whipping, and such.
Most people aren't built to fool with no one who isn't their immediate family on that level.
