when alexander first saw bucephalus and found out that his dad philip didn’t want to buy the horse because he was unmanageable, he kept saying that it sure would be a shame to give up such an awesome horse
he kept saying this until philip was like well alex do you think you’re so great that you can tame this horse
of course alexander said yes
alexander tamed this Troubled Horse Who Lets No One Else Handle Him by being gentle to him and and turning him away from his shadow
literally like a Horse Girl Movie ™
philip was so amazed by this that he told alex that macedonia was clearly too small of a kingdom for him
