At this time of year when I return from my summer holiday I do writing warm up exercises with any souvenirs I bought or found. This year it's been old letters and postcards with messages. I found an envelope with three beautifully written letters from a daughter to her mother on Mother's day. They were about 300 miles from where they were written and sent. The tone was sweet with a few moans about studying. The writing and paper are exquisite.
Also there is a story in there.
Next time you're at a junk sale have a look for letters. See if you can find a story in them.
