Doug - all I meant was that it's unfortunate when what is intended as a light-hearted conversational gambit turns out, on reflection, not to have been a good idea. Which is what I assume has happened. It happens to most people sometimes, but in verbal conversation it is more transient. Unfortunately, in threads things persist & as I was reading the responses I was feeling more & more sorry for the hapless original poster. I've been in the same boat on occasion (well, similar anyway) and just wanted to express some fellow-feeling.
As you say, it has proved a worthwhile thread - and I'm sure has been a very timely reminder of the consequences of drink-driving - but I think really I was just responding to your 'Arggggg' posting when it came back after three months. Kris
