For the second part, I'd add: people from your country.

If there's a gathering of less than 20 people from my country, I love everyone. 20-50 and I start hyperventilating. More than 50, and I make and execute elaborate plans to get out at any costs.

Travellers often don't like gatherings of people from their own country. I overheard this on a train, in Japanese from a conversation between two girls ... "minna nihonjin da kara, ikitakunai". (Everyone will be Japanese there, so I don't want to go.)
