If I knew you were going to act like that I wouldn't have bothered writing in the first place.

Sit down _away_ from your code. Draw out the problem on _paper_. Act it out.

I actually like to act it out with one person per object, but sometimes that is not feasible.

If you can't figure it out from there, you're probably not drawing the problem out correctly or completely.
