But if I posed a question that would help with a visual, then I could do that here.
Of course you are free to respond, even to a question directed to me. But you didn't need to be nasty.
No, but it's so much fun sometimes. You're actually using the topic to ask questions and get advice, while he's not being useful at all, hence why he's thick and you aren't. I don't have any salient points to add on the topic, so I took it off into a direction entertaining to me and Etoile, but it's quite easy to have two or more separate discussions going on at once (not to mention that hijacking threads is a long and honoured tradition 'round these parts).
