"I cannot hear you at all. I had no idea anything out of the ordinary was being communicated. Although I suppose I should recontextualize some instances of your people staring at each other and then parting as something other than your superior hearing and prolonged acquaintance, in retrospect."
Finally he settles on something. He and Irissë are in Valimar on holiday The searing heat of the Trees is making the day almost unbearable, and they jump into a river fully clothed and then lie on the shore, drying until their clothes are no longer transparent, warm and safe and unimaginably far from here.

If the particular visual metaphor doesn't work for you, that's fine: the important part is thinking of your thoughts as possible to view in two domains, a public one and a private one. Some people imagine reaching for their thoughts with their left as opposed to their right hand; some people have a public color and a private color.

"Wouldn't it reduce the shock if I were suggesting something?"
"I wouldn't kill you. Dodging is faster than drawing my own weapon and I assume you wouldn't press the attack. What things do shock and upset children born to Valinor, anyway?"
