TIA has a sound approach to this issue and TIA, I'm sure, will take me on if I say anything worth taking on. I love constructive challenges to my idiocy. As for your post being challenging, the only challenging thing about you is that you will never be content with anything I ever say and, frankly, I haven't got from now 'til eternity, and in any case I'd only be repeating myself. I'm not Keith, you know. I have bikes to ride, grass to cut, wild flowers to admire.
