Why No-one Should Ever Rely on Me for Proof-reading

Because I see what I expect to see rather than what's actually there.

Take the "Some Saints for September" section over there on the left hand column.  Miss Chadwick's drawings for September do reside there at the moment.  But for a short while on this 4th day of September her drawings for Septuagesima graced that space.  Both words do, in fact, begin with "Sept".  But as I have now learned -- alas, not for the first time -- one does have to read the entire word in order to post the correct picture.
