Riley

The greatest girl in the entire world. Giving, loving, caring... the type of person that gives one hope in humanity. Lastly, the girl that I love and cherish to no end.

Riley of Virginia is the coolest person on the planet.

Riley

Well.... Riley is all round goofy. Riley is very hot and will do anything to make you smile and laugh. He seems nerdy until you get to know him... he's still kinda nerdy. But he's just amazing and a great friend.

Oh you know Riley... Ya the goofy guy over there... I mean he's pretty hot too.
