Sometimes, some classic books lie long before you pick them up from your shelf. That was (in my case) with A Tale of Two Cities. And, to tell you the truth, I read it now only because my friend grumbled that the book was boring. 
 He is wrong, of course ;-) . I don't understand how someone could tell it is a boring book. There isn't time to be bored. We have an interesting plot, quite multiplex characters, a historical background. What could someone wish more? 
 I know, what I would wish more. This story could have been a great material for a long novel. I dreamt of reading about a romance between Charles and Lucie. And, first of all, I would like to know more, to read more about Carton. 
 But, as a short story it is a masterpiece. And of course, descriptions of a sociological and psychological basis of revolution and human behavior are brilliant. But it is Charles Dickens, after all. So, if you are waiting for a good time to read it, stop waiting ;-)
