The works of others; the kindness of strangers.
There are bad days, days we wish to forget. A good writer can turn a horrid day into one to remember.
Katherine Fritz is such a writer, and I would like to recommend her post about a really bad day. It is well worth a read, but then so is the rest of her blog.
We are all reliant more than we like to admit on the kindness of strangers. It is always worth remembering that strangers equally rely on us.
