white horses and brave knights

Are there no more white horses charging,charging, steady but wild-eyed. beneath white hatted riders splitting raw win, or roping wild tide? Do they still roam among us? but like Tinkerbell just out of sight unless you believe, and clap your hands? or throw pennies in a wishing well? I did believe, I did belive. I hoarded found pennies wished on a million first stars and challenged talisman you could not conceive but if you ride no white horse. If your hat isn't white then I pretend they don't exist. and to keep my own castle devoid of a white stallion and devoid of a brave knight.
