Eek, Del. Go in there with good thoughts in your head. Be quiet and confident, yet trepidatious and kind and forgiving. Not a small task, I know, but try to keep it in perspective in terms of all of the other gigantic nightmares that you're living through right now.
Heck, there's lots of folks in this world who picture homeless and helpless kittens in their minds when they're trying to think of lovely things in life, things to live for, to scoop up and cuddle with and give love to, blah blah blah...
Remember the mantra -- "For every problem, there IS a solution. For every problem, there IS a solution. For every problem, there IS a solution."
Good luck, girl. Let us know how it turns out manana.
