Galactic Diplomacy 101: The Etiquette Guide

Chapter 1: Proper Greeting Protocols

In the galaxy, a good first impression is everything. When greeting a dignitary from a distant planet, make sure to:

Avoid sudden movements, as they can trigger the 'Galactic Fart Defense System.'
Use the correct number of tentacles to display respect. Two or four is acceptable, three is impolite.
Address them by their highest title (e.g., 'Your Imperial Majesty, Supreme Commander of the Andromedian Empire').

Chapter 2: The Art of Small Talk

Engaging in witty banter with a fellow alien can be a delicate art. Remember:

Avoid discussing the finer points of 'Transdimensional Accounting' unless you're absolutely certain they'll appreciate it.
Never, ever bring up the 'Great G'norchian Fiasco' of 3456 unless they're a G'norchian.
When in doubt, stick to 'The weather, it's always terrible.'
