David, I apologise for being a bit sarcy, and perhaps you're right regarding semantics. I have no wish to row with you whatsoever, but sometimes the tone of your posts just makes me feel like you're talking down at me, and I feel patronised, and probably react as such. Most likely things just getting lost in translation, as they so often do in text, especially if we don't put a ;-) at the end of everything we bloody well say.
