A book is a pleasure to share

If you read a book and it influences you greatly, or even if you just enjoy it very much, you long to persuade others to read it too. A book is not just to be read privately in the evening in front of the fire. It is a pleasure to be shared, it is the cement that bonds person to person in greater sympathy and understanding. 

Christopher Milne, The Enchanted Places (1974), p. 144
