similar to your husband's experience combined with that of BuzzCzar and Gandalf - a little ad hoc, some formal training and apprenticeship and dominant since I slapped the nurse back when I was born. I really enjoy seminars/displays...learned firework from a friend who is damned good at it - he did a training display two years ago...it was superb (pity he is a boring public speaker though).

and yes - I think about the psych aspects all the time
