Found this on Facebook. I don't personally identify with a all of the drinking references (except for the first one) but whew, I sure matched a lot of the rest of it:
You know you're Latvian when...
"you've gotten drunk before you hit puberty"
"you only had piragi for a meal"
"you have brown and green pottery in your house"
"your grandparents tell you it was better in the old country"
"you have a big ego"
"you say you're just going to have one beer"
"you have to fight the russians at your school"
"you've celebrated John's day since you can remember"
"people ask you if you speak latin instead of Latvian"
"you go to church just for the social scene"
"your grandmother owns A LOT of jewelry"
"you have the natural ability to play volleyball"
"you love hockey"
"you do folk dancing on your free time"
"you say, 'I'm Latvian need I say more'"
"you switch your languages in a conversation"
"you talk about people that are right there in another language"
"you listen to brainstorm, Prata Vetra"
"you can sing the latvian national anthem by heart"
"you go to a different high school on friday nights"
"you go to three rivers, michigan just to party"
"you're really hot"
"your parents would kill you if you married a russian"
"your interests have to do with anything latvian"
