Michael Martensen: Dad, it's okay to cry when you're sad

When I was sad, I could cry. This book introduces the lives of his daughter, four-year-old Sofia, who moved all of Germany. Sofia, who was diagnosed with leukemia at the age of nine months and still had no sense of humor or laughter, tells us what is most important in her life. When you're sad, you can cry, and you can tell us that if you learn to live through the 1460-day record with Sofia and to love life's passions and wills and moments of life, you will be able to cope with any hardship and problems.
