have a mind like a sieve

Memory constantly fails

To have a mind like a sieve is to be forgetful—information passes through without being retained, like water through a strainer.

I have a mind like a sieve; I forgot our anniversary again.

The phrase is self-deprecating and casual, typically describing everyday forgetfulness rather than serious memory problems.
