"My birthday is in February. And besides, this is July."

"The one in the supply closet?"
"That's the one. On 22 December, 2012, it's going to open... and stay open."
"But it never stays open."
"I know."
"Where will it open to?"
"I don't know for sure," Charlie said, nervously eying the door. "As best I can determine... nowhere at all."
