Take it or leave it.
1. If you find yourself nominated by the President for a key government post and are forced to go office-to-office making nice with U.S. senators, avoid sitting on a couch. It makes you look lonely, friendless and potentially cootie-ridden.
2. If you've been busted in the past for falling asleep in public, try to avoid slouching or in any way letting your chin touch your chest.
3. Avoid appearing in front of the picture of someone who makes you look weak and feckless by comparison.
4. If a Greenpeace activist interrupts a photo session involving heads of states assembled for the "IV Summit of the European Union, Latin America and the Caribbean" in order to protest pulpmill pollution, I say you let the lady speak.
