Here is why I think this:
- saying things in a way is different than understanding them
- communication is happening on all channels: verbal, non-verbal including context, rhythm, tone, time, moods ... So only being honest verbal does not assure that the other will understand the same way the non-verbal or the context
- I understand that maybe mathematics is a honest way of communication. But takes a lot of practice (building concepts one from another and all from a starting point) from everybody to understand from a book the same things. And this is not usually possible between two people. Maybe can be done between long term partners
- I think focusing on the I without putting effort into making sure how the other understands be a trap of deluding ourselves that we are honest. We are honest when the others also understood what we said and only after that they can truly respond to who we are. At least this is my believe.
