It's a shame I didn't finish this one faster. A really good book. In the beginning I wasn't sure I understand where all this is going - why should I care about these kids, their childish adventures? The storytelling manner was also quite childish. That's understandable, of course, because it's told from the point of view of a 6-7 year old kiddo. 
 Closer to the middle of the story I finally started getting where all this is going and what's it all about. I think it's a very rare combination when a story narrated by a child is actually a story for grown-ups discussing such serious problems as discrimination by race and general injustice, violence, rape. 
 But I actually enjoyed the second theme of the story even more. To Kill a Mockingbird shows us that children are, unfortunately, mostly the only ones in the world who can really tell the difference between good and bad, who are capable of empathy and real emotions. This is what makes this story popular nowadays - people grow up and become indifferent to all that is sad, evil and horrible out there. They build a wall around themselves and spend their lives convincing themselves that they don't care. Children never do it. I think every single person should bring these traits with them into their adult life. And I don't understand why it doesn't happen. 
 Another thing. Atticus is one of the best father figures in literature for me now. Honestly, he's the embodiment of a perfect father: strict, but caring, he is able to balance these traits. He's wise, he has high moral standards and rules, which he follows and therefore sets an example for his children. I am very very fond of him. 
 All in all, it's unquestionable why this book is a world classic and still being read in the 21st century. People will read and relate to it until they learn to be... to be better than they are, I guess. :-)
