Greetings friend @carlos84, very good your comment about this section of the book, there are some people who confuse sincerity with hostility, they believe that saying things in a rude way is synonymous with absolute sincerity.

I think without making the mistake of believing that I have the absolute truth, that we can be sincere with people by telling them the things that they deserve in a courteous, respectful and frontal way. How they say that courtesy does not take away from courage.

I like your analysis, my friend. See you later, blessings! 🤝
