Remeber? Ohh, I wouldn't do that! Remebering's dangerous, I find the past such worrying, anxious place... Memories can be vile, repulsive little brutes...
But can we live without them? Memories are what our reason is base upon. If we can't face them, we deny reason itself!
So when you find yourself locked onto an unpleasant train of thought, heading for the places in your past where the screaming is unbearable, remember there's always Madness. Madness is the emergency exit.
