When we feel discouraged to speak

We perhaps don't realise that seeing another person's face can discourage us from speaking the truth. We may hold back and edit our presentation in the light of their reactions.

With Sigmund Freud's example in mind, we should find our own forms of horizontal conversation. After dinner, we might suggest that we all go and lie down somewhere and become newly conscious of voices and nuances when we don't have to look at others' expressions.
