Memory is an interesting thing. It’s really just a re-imagining of something that doesn’t exist, i.e.: the past. It’s also interesting that it seems to start failing us at the point in life when we might actually have time to enjoy it – when we’re old.

It isn’t so astonishing, the number of things that I can remember, as the number of things I can remember that aren’t so.

When I was younger, I could remember anything, whether it had happened or not.

- Mark Twain

A clear conscience is usually the sign of a bad memory.
-Steven Wright

Memory is a crazy woman that hoards colored rags and throws away food.
-Austin O’Malley

The existence of forgetting has never been proved:  We only know that some things don’t come to mind when we want them.
-Friedrich Nietzsche

Memory is what tells a man that his wife’s birthday was yesterday.
-Mario Rocco
