Досвидания das-vi-DA-niya Pretty common, can be used for pretty much any situation, whether informal or formal. I would advise against using it with family or friends though. Пока pa-KAH Best used in pretty much any informal situations, pakah is perfect when speaking to anyone whom you would address as ты (idk how to replicate the sound using english letters, so take this crusty vocaroo) https://voca.ro/105bHnkdaIcx So you can say this to kids, family friends, pretty much anyone if it's informal. That's all for today, so peace out ma peeps! ~TotallYEET
