My pleasure comes from seeing my code used in ways I never thought of. Why ?

Two reasons

• my code is being used - yay
• its good/robust enough to be retasked to some area I didnt envision

I think the 'stangest' feeling of pleasure I got was when I was told that the data entry operators had changed their work habits to maximise their 'statistics', as reported by my new performance management tool - somehow, without knowing anything about my code, but just seeing their performance reports, they started 'adapting' or 'evolving' new ways of doing their data entry (keying) so that their stats were higher without them actually working any harder - fascinating
