Ah. So the idea is that small isn't always best, large isn't always
best, but being able to pick the best size for what you're doing is

Next time I will remember to burn the incense and sacrifice the chicken
before invoking your name, to warn you. From inside an inscribed
pentagram, of course. Now where did I put that athame...;-)

Or would that be Mail Answer Syndrome? That's what I have, for sure.
Even on vaction.
OTOH, there is something "better", somehow, about answering email via a
wireless DSL link from the living room of a cottage that looks out over
Lake Huron, where just a few hours before I was catching a dozen or so
mid-size smallmouth bass in about an hour of fishing as the sun set over
the water. Letting them all go -- I don't keep anything under about 3
pounds up here, but the 1-2 pounders are wonderful fun to catch and
release, wading along in 3-4 foot deep water.
Y'know, except for actually going to a classroom and teaching, I could
do most of the rest of what I do sitting right where I'm sitting now, in
between trips down to the lake in search of dinner...
