We’re so caught up in our everyday lives that events of the past, like ancient stars that have burned out, are no longer in orbit around our minds. There are just too many things we have to think about every day, too many new things we have to learn. New styles, new information, new technology, new terminology … But still, no matter how much time passes, no matter what takes place in the interim, there are some things we can never assign to oblivion, memories we can never rub away. They remain with us forever, like a touchstone.
