:D You do realize that I am helping you pass the time by doing what you do best ... or, very well, anyway ... teaching! Right?
For myself, if I have to answer questions, I start thinking of things I hadn't thought of for a long time, little tips from my dad, or a friend, or a book I read ....
I would tell you to hang in there, but I know you have already tied the knot at the end of the rope and are hanging as much as possible.
