All Latvians hate their country (and are going to leave it soon), Latvian women are beautiful, Latvian men are taller and better looking than average European, everyone is able to speak three languages (English, Latvian, Russian). Lithuanians call Latvians horse heads. Estonians think that Latvians have six toes, add -s to every word and have strange obsession with Latvian word for ice cream, so some of them appear to think that Latvians themselves must be obsessed with ice cream.
P.S. Estonians are the ones who think they get slow in the winter (they also think they are introvert and blame it all on the weather and cloudy of sky), they are also the ones who let the monument hell lose, while in Lithuania, for example, they have very few Russians to hate and no SS issues, you are confusing Baltic states with one another pretty heavily
P.S.S. I've heard about moustache being typical Latvian male only once before (fairly recently), describing unemployed, also said they wore all jeans, sounded kind of like people from 80s, possibly it only applies to certain social class (might be kind of like redneck for Americans)
