peräpäähän

"Peräpäähän" is a Finnish idiom that translates to "to the back of one's head" in English. It is used to describe a situation where someone is completely oblivious or unaware of a particular issue or problem. The phrase is often used to express that someone is so focused on their own concerns or distractions that they fail to notice or address a more pressing matter.

The idiom is commonly employed in everyday conversations to highlight the lack of attention or awareness towards a significant problem. It can be used in various contexts, such as work, social situations, or personal relationships, to point out that someone is not paying enough attention to a critical issue.

For example, if a colleague is constantly distracted by their phone while a project deadline approaches, one might say, "Älä mene peräpäähän, sinun pitää huolehtia projektista!" which translates to "Don't go to the back of your head, you need to take care of the project!"

The phrase is a useful tool for emphasizing the importance of being attentive and mindful in one's actions and surroundings. It serves as a reminder to stay focused and address any issues that may arise.
