Here is an idea.
What if you didn’t trust someone to keep a secret?
Just tell them something totally false about someone else.
Then sit back and wait to hear back from the person you spread the rumor about.
When you do. Explain how you were just testing the other person’s discretion.
Oh…
I guess that won’t work either. Then no one will ever trust what you say.
Somehow things always makes so much more sense when you wake up from a dream.
