Russian (what do we remember)

Russians native language is Russian
They are pessimistic
It is rude to extend your hand in front of them during a conversation
They like to wear American shorts
Call each other by full name
Are polite and address each other Mrs and Mr. and like to be called by such
Impolite to talk and have your hands in your pockets
Orthodox primary religion
Bad luck to shake hands across the doorway
Like to dress formally
