23 - speak synchronously
Everyone speaks for himslef. The reason to argue is preprogrammed. If two persons speak synchronously they share the same opinion and won´t argue. Their voice gets becomes even more important. If you speak together, you speak for yourself, for and with the person next to you and by this means everybody. It is not me speaking - it´s it. Speaking synchronously softens the faults when two strong egos crash and can be the beginning of a harmonic living together.
