We form like Voltron
Smile! The leaders of the 8 most badass countries on the planet are getting together to continue being the best, and will discuss improving the lives of the other countries over brunch. Meanwhile, the unhappy and/or the adventurous protest. If only I could report first hand, 'embedded' with either of these two unique groups of people-- what a journalistic opportunity. I'm sure I'd have fun with both of them, but probably succeed in talking sense to neither.
As to whether the leaders or protesters have more fun, it's anybody's guess. The leaders get to resolve complex geopolitical nightmares by working as a team; the protesters get to take off from work to taunt armed police into violent action. Everybody wins!
