It's a secret, you know. We don't know the insides of other people. We don't know their thoughts, their fears, their worries. We see the outside, and onto that we see projected certainty. We see, we doubt, our own validity, but when it comes to others even their own statements of hesitance and personal uncertainty may not be recognised by us, not internalised and realised as our shared truth.
We doubt we're real. We doubt we're valid. We think we're making it up, but other's aren't.
