[Margaret Pilkington]

Yes, by speaking to one another face to face, because when we speak face to face we are not just listening to what is being said we are observing non verbal cues......and these often soften the words that are being said.
You cannot pick up nuances in a text message, and that is why the Internet and mobile phone are a bad way of communicating.
Humans believe body language so if what you are saying is not mirrored by your body language, then your brain will believe the non verbal stuff over what your mouth is saying.
