All Memories Fade

Nothing is as intense as actually experiencing something. You see things as they are with your eyes. You smell the air, hear the sounds, and so on. All of your senses are firing all at once, creating a cacophony of stimuli. 

And as soon as an experience is over, it is a memory. Your mind stores the thoughts and feelings of what you just experienced to think about, reflect over, and maybe even learn from. The problem with memories is that they are impermanent.

All memories fade. The mind simply can't hold on to all of that information for every single second of every single day. The mind holds on to memories from significant events longer, but eventually they, too, fade away. 

You might think that even a traumatic event is permanently seared into your mind - after all, you still remember it so vividly and strongly - but when you talk to somebody else who also experienced it ten years later, they remember things very differently. 

No matter how iron-tight you think even the smallest part of your mind is, it simply isn't. And that is precisely the reason that we must write.
