So it is, @kouba01. When we read part of those passages we believe not only to be within the conversation, but we sense that it is a private conversation to which few should have access. With your comment I remembered that I should have put a part of the preface that this book has and that says:

This book is all about the past. The homeland and childhood -both already very distant- are its background...

Thank you for your always accurate and valuable comments. Greetings.
