go in one ear and out the other

Not retained mentally

To go in one ear and out the other is to be heard but not retained or heeded.

The phrase describes information that fails to register: I've told him a hundred times, but it goes in one ear and out the other.

It often implies frustration with someone's inattention or unwillingness to listen.
