Might seem like a random thought. Then again it might not. Depends on how and to what applied.
I did a Google search on “Inner Circle”.
Your Inner Circle. These are the people who are very close to you, who understand you, people who you trust to always be there for you when you need them. The number of friends in your inner circle should be small, typically less than 5 people. Maybe you only identify one person—that’s ok.
