 I will remember the most what she wrote about monotonous and uneventful childhood/school. I haven't thought about it before. But it is so true.

 I am positively surprised with this book. Perfect for a lovely day or to make your day lovely. 
 For more and nicer you can read for example in review by Anne or Tadiana Night Owl.
