In 1976 I married young and moved with my wife half way accross the country. My mother would write almost every week with everday information along with a usual dose of advice. Unfortunatally I usually only skimmed through the letters and they ended in the trash after a few days or weeks. Ten years later in the mid 80s my mother died from injuries resulting from an automobile accident.
Even now almost 20 years after her death it makes me very sad that I did not save any of those letters. So my do-over would be to save those letters and have a priceless window to the past.
