18 months

What means 5 years in the eyes of One Direction. It is a space of time, in which a band go on hiatus and lie about how long they will be gone.

“you know one direction went on a hiatus for 18 months?”
“yeah i do but i think it will be longer”

September 18

People born on this day stand at the pinnacle of society. Elites in every single way. You’ll always want this person as a friend but never as an enemy.

John: “yo Kevin is amazing! He’s so good at everything!”
Patrick: “I mean it makes sense, he was born on September 18 after all.”
