How do you feel when there are no other ethnicities around beside your own?

At school or church or in a pub on a certain side of town, maybe at that restaurant you used to go to when you were a kid, or an odd business convention, on a trip, or a major in-law gathering or whatever the case may be.. sometimes you just end up surrounded by people who share your ethnicity and no one else!

What is it like compared to when things are more diverse? Do you notice anything different about the energy in the room? Do you enjoy it more or less? Are you disappointed? Ecstatic? Do racial jokes tend to increase or decrease in the group? Do people get more or less drunk? Do you even notice, really? Anything at all?

(Feel free to omit your race if you want, no real rules)
