I think it unmannerly to sigh & denounce me as 'thick as a brick' for not knowing something which you did — & which is, btw, usually differently perceived over here anyhow. Thank you Tug for your support. 'GUEST#6' & 'pdq', I think you should be fucking well ashamed of yourselves — but I don't expect you are; never mind, I am ashamed enuff on your behalfs to do for all...
