Listens like a brick

1. Fails to obey commands. Sits there and seems to listen, but then fails to respond in a commensurate way.

2. Hears good advice, then blatantly ignores it - and usually pays the price.

"That kid listens like a brick. I told him to stop wiping snot on the towels, and here it is again!"

"So did you hear? Sandy's house got robbed - again."
"Yeah, well, she listens like a brick. The police told her three times already to keep her doors locked. You'd think she would've learned by now."
