What does "on that note" mean?
"On that note" is an expression that is used to segue or transition conversation from one topic to another. For example, it might be used when a person wants to move the topic of conversation onto something else or to end the conversation entirely, like how the speaker in this video does here. Ex: On that note, it's bed time for me. Good night, guys. Ex: On that note, I would like to move onto the conclusion of my presentation.
