“Today we're going to try sitting with silence a bit. Don't worry about any moments of dead air in the conversation.”

“Sealing up the house so perfectly, without planning for any active ventilation to replace the passive ventilation that you have eliminated, is not a good idea, because it encourages pockets of dead air.
