Is there someone in your life that knows most if not all your secrets? should you take them out to prevent them being used against you?

Hmm they know many, not all. I usually know far more than others do. It's easy to know things when you live with someone or are close. But knowing things about semi strangers that they would be shocked about, well.... 🕵️‍♀️
I can be like a blood hound.
