Out of the Blue (2023)

The phrase "Out of the Blue" typically refers to something that happens suddenly or unexpectedly, without any warning or prior indication. For example, if you receive a phone call from an old friend who you haven't spoken to in years, that call could be described as coming "Out of the Blue." The phrase comes from the idea of something appearing suddenly from a clear blue sky, without any clouds or other signs of disturbance to indicate its arrival.
