The nice thing about Chicago is that if you're invited to a retirement party for an elected official, there's little chance you'll find yourself wondering, "Should I get a retirement present?" Much less, "What would be an appropriate gift for the occasion?"
Because the answers always will be: "Duh." And: "Cash."
If you need a concise parable to remind you of this advice, I just happen to have one, about the ethically awesome Alderman William J.P. Banks. Kind of cool that his last name is Banks, isn't it?*
Hard to imagine that this is the same city that gave Governor Blagojevich his start in politics.
* Also, I think J.P. probably stands for "Just Pay."
