Like a house full of filing cabinets, our minds offer easy access to certain memories — your best friend's smile, the name of your favorite chocolate cake...

Other memories prove more elusive, perhaps stored in a cellar or forgotten corridor.

But they're all there. Nothing is forgotten.

The simple nudge of a frosty day and a familiar stroll may be all we need to bring lovely recollections from the deepest files and create space where fresh moments will be forever saved.
