Zitat von David Levithan - Will Grayson, Will Grayson

"Deshalb nennen wir Menschen Ex, vermute ich - weil die Pfade des X sich kreuzen, aber am Ende auseinander gehen."

"This is why we call people exes, I guess - because the paths that cross in the middle end up separating at the end. It's too easy to see an X as a cross-out. It's not, because there's no way to cross out something like that. The X is a diagram of two paths."
