Hi Brendan
My cold is now on its 20th day and I'm coughing nicely, but at least I'm no longer feeling poorly. I did manage a trip to the theatre here in Exeter last night to see an interesting and very different version of The Importance of Being Earnest. I was worried my coughing would annoy people, but there was so much laughter and applause I managed to cough then. The group (Say it Again, Sorry) are on tour and if you can catch them I would recommend it.
Thanks for your explanation of 18ac. I did get it from an earlier thread.
