Mish: Memory is a strange mechanism. You can never predict which of your experiences you will remember and how. It is a mysterious process in which certain things you wished to remain in your memory are irretrievably forgotten and something that you would rather forget becomes glued to your consciousness and keeps coming back to your mind when you need it the least.
A squeaky voice: Better not to bother with memories too much. They will manage without your assistance - just allow them some time to ripen and appear on the surface....and then enjoy the good ones :)
