'Companions. Confidantes. Allies.
Friends.
By whatever name, they pick you up when you're down, expand your horizons, and support you when you're in dire straits.
In short, they weaken you. They betray you.
They rob you of opportunities for growth. Opportunities to prove your strength. Your will.
The Great Beyond cares nothing for your friends. It is emptiness.
Loneliness.
YOU are the only constant.
All else is dross.'
— from 'Echoes of the Great Beyond' by Harriet Morse

Harriet 's philosophy? Dump your friends. They'll always disappoint you.
