We got some mixed news today, so we went with following sentence:
”забыть о вчерашнем. завтра будет новый день”
”Forget yesterday, it will be a new day tomorrow”
”Unohda eilinen, huomenna on uusi päivä”
забыть - to forget - unohda (unohtaa)
вчерашнем - yesterday - eilinen
будет - future tense of ’to be’ - on note that there is no future tense in Finnish
