It may be coincidence...
Or it might be divine fate. Who knows? Perhaps those three old women wove a tapestry so finely and wove two lives beautifully together until that very moment. Your lives were separate at one time, yet fate saw it fit to bring you two together for this very moment. To choose those characters you love and adore. To find this masterpiece of a game we call TF2. To transfer those characters you look up to as sprays, and to play on this particular server. Time itself bent for this fated meeting to take place. The two of you coincided, posting your respective sprays upon that virtual wall, forever making a fixed event that shall never be erased. An event so important that multiple universes shall repeat this very event over and over again, and you were a part of it. Maybe fate didn't give you a golden sword, or a vampire friend. But something about this event in time is magical, it's wondrous. It's............Algebraic.
tl;dr - Cool, I'm bored.
