This will probably, at some point, expand into a "Care and Feeding of Your
Geek" article; for now it's just some notes on flow and how it
relates. the Wikipedia article defines flow as "the mental state
of operation in which the person is fully immersed in what he or she is
doing, characterized by a feeling of energized focus, full involvement,
and success in the process of the activity." It's often described as
"losing oneself" in the activity.
There's more. Go read it. I'll wait.
Most geeky activities -- programming, gaming, art, music, dance, reading
-- are enhanced by the kind of active concentration that characterizes
flow. Flow, in turn, is often one of the beneficial side-effects of Asperger
syndrome, a mild form of which is common among geeks.
There are three things you have to know about flow and your geek.
First, if your geek is concentrating on something, you aren't there.
Neither is he. (I'm going to use "he" to refer to your geek because
I'm male, and this is partly directed to my keeper wife; adjust
as needed.) Your geek may seem to be present; he may even be
able to carry on what appears to be a brief conversation. Don't be
fooled. Almost all of his mind is lost in what he's doing. Don't be
surprised if he doesn't remember a thing you said afterwards.
Second, getting yanked out of a flow state hurts. If you break
your geek's concentration, expect to be snapped at. It has nothing to do
with you: he'd snap at a dog, his mother, or a phone call saying that he's
won the lottery. The sensation, if you haven't felt it yourself, is a lot
like being awakened from an exceedingly pleasant dream by a loud noise
that can't be immediately identified. Your geek may not even remember
what he says at that moment -- he'll be sorry about it, but he really
didn't know what he was saying. You may have noticed him walking into
lampposts while reading a book, too.
Third, however, is that flow is the reason why geeks often make
surprisingly good lovers. Consider the implications of having 100% of his
attention on you. If you ask him what he's thinking about, he
might not be able to answer. If you ask him why he thought to scratch you
just exactly there where you needed it, he probably won't be able
to answer that one either. If you ask him to stop, ... never mind; you
probably won't want to.
