THE MOST BEAUTIFUL BOY OF ALL TIME. often very nerdy and weird-looking during early childhood, but always ends up really turning himself around as he gets older. before you know it, he will have transformed into a cool, gorgeous, amazing guy! a HP is a true catch. hold onto him even if it is in those unfortunate early years that you find yourself with him.
is that REALLY HP? he got so much hotter since the last time i saw him!

yeah that sounds like an HP alright...
