deaf as a post
Totally without hearing
Deaf as a post describes someone who cannot hear at all, or who is choosing not to listen.
The comparison to a post—an inanimate wooden stake—emphasizes complete absence of hearing or response: Don't bother whispering, she's deaf as a post.
Often used with affectionate exasperation about elderly relatives or anyone pointedly ignoring you.
