And of course in the end there's the plain meaning. The speaker meant to stop the subject from misbehaving by parents. It doesn't exactly follow the "implicit" line - if you say "could you pass the salt please" you mean you want to have the salt passed to you, no hidden motives.

She's been put through the wringer more than once. Usually the idiom refers to a single harrowing experience. A "wringer" or mangler was a machine used to squeeze water from washed and rinsed clothing.
