Dear canary:

Your answers lead me to better understanding, so thank you (I like understanding, not confusion!) I will be away from the computer for a while, and the next opportunity I will have to be focused enough to reply to you further is Sat morning, which is in about 16 hours from now. I will be back to you then, and if anything comes up before I return, anything you want to add: please do (it will not be too much for me, no worries!)
