brain like a sieve

Can't remember anything

A brain like a sieve fails to retain information, letting memories and facts slip through like water through mesh.

The phrase describes persistent forgetfulness: I've got a brain like a sieve—I've already forgotten her name.

Sometimes shortened to my mind is a sieve.
