A sieve for a brain 🕳️🧠

Meaning

Someone who has a poor memory or is easily distracted and cannot retain information.

Origin

Imagine ancient times, before modern record-keeping, when knowledge was precious and often held only in memory. People would lament the loss of vital information, comparing the mind's inability to hold onto thoughts to the way a coarse sieve lets water (or ideas) drain away uselessly. It painted a vivid picture of mental porousness, where facts and memories would simply slip through the cracks, leaving nothing behind but an empty space where understanding should be. This stark, relatable image became a popular way to describe forgetfulness and a lack of retention.
