An MS PM
Is the type of person who will shake your hand
And look deep into your eyes
And be all nice and friendly with you
Just so they can learn about your weaknesses
To use them against you.
A producer is the type of person who, when one person on the team does something that's vaguely against policy (but is fucking irrelevant so they should really just do nothing), rather than just talk to that person about directly and nicely, will send out an email to the entire team saying "Just a friendly reminder about our company policy, blah blah blah".
