Yep. You said it better than I was about to (not just this line, but the 
whole post). I was going to say "people don't 'have' bank accounts; they 
have the intelligence to perform transactions by visiting a web site and 
  entering a password.

As you say, the location of such intelligence is a question that can 
wait until someone starts poking around in the interpreter.

For a beginner, it's more important to have a _model_ of how method 
lookup works (model in the sense of science, not rails). If the easiest 
way of stating this model is in terms of what methods an object has (and 
what class they were acquired from), so be it.
