Why the Horse's eyes are on the side of its head ?

I think that horse should not be so sly or show off , in future if anyone show off no one would also like it , Horse deserve it to be tricked . But i think that if parrot and cougar would have wanted to play a trick , they should not have don anything to horse that would affect its eyes . The reason why i said that was because if cougar would not have run away , horse would have done a very horrible revenge and they both would be fighting over and over again . In the first place they should not have done a trick , they should have told straight on its face that it is annoying and irritating . And they could have ask horse to stop showing of . Horse would have thought twice about its character and stop being a show of . Thats all i would have to say about this story (:
