APAD:Ignorance is bliss

Ignorance is bliss.

If you don’t know about something, you don’t need to bother about it. In other words, if you’re unaware of something, it won’t cause you stress. This proverb, however, is often used in the opposite way – ignorance is not bliss.

Example: I didn’t know that the neighbor next door was involved in criminal activities. Sometimes, ignorance is bliss.
