An interesting riddle (Well, I thought it was interesting)?

Nails in a horses hooves holding the horseshoes on.

well my favourite character is *HARRY POTTER ofcourse harry-the boy who lived is my most favourite character. not because he is the boy who lived or the choosen one but because he is a real saviour of the wizarding world. i mean he is nearly a perfect person with virtues and principles and is very good at heart. usually parentless children who are harrassed by relatives turn out to be bend in types, weak and vulnerable. but harry on the other hand is very brave and determined boy. though he has his own bit of traits like recklessness, etc so what everyone have their own traits. he faced a lot of problems in life, even then he never lost courage. his humanity is limitless Harry Potter is really a very inspirational character. (This is my favourite quote by harry) "I'm going to keep going until I succeed - or die. Don't think I don't know how this might end. I've known it for years." ~ HP and the deathly hallows. well then there are others too *dumbledore- he is a genius, brilliant and all. quotable character as you said. after all he has got style. no one can deny that. *ron weasley- he is a humourous fellow. a bit of childishness is there though. but he is a kindhearted person. that is why hermoine fell for him. *hermione granger- the know-it-all girl. she is a nerd but very brave though. *fred and george weasley- (together because they are inseparable. only death could part them and it did so too.) there is no doubt the twins rock- Babbling bumbling band of baboons. the real trouble makers. these two can do anything even that which is impossible. pranksters, inventors, even jokesters. they have got an amazing sense of humour. they are the coolest and the best. i like other characters too like sirius, ginny, molly, arthur, neville etc but the starred ones are irresistably favourite
