Sometimes in an effort to be friendly we talk too much, and sometimes the people we " spill our guts to" are not friendly. They will listen an look as we share with them certain knowledge or blessings God has given us. The next thing you know certain ideas we have been working on have been submitted to the boss under someone else's name or you go to buy something you have been saving for only to find your "friend" got there first. Or worse yet you come home to find that someone has broken in and robbed you of your prized possessions.
Don't be too friendly., Don't be too open, Don't talk too much.
It's best to be a better listener than a speaker.
