"No mean hugs."

You know what I'm talking about: the kids have been arguing, mom or dad suggests they be nice to each other instead, you know, just to see if that makes anyone any happier; the kids make that agreement to each other and consent to hug, only mom or dad can tell that they're both still angry and really just want to take this opportunity to 'hug' the fake smile right off brother/sister's face so mom or dad intervenes one more small time, making the above request and monitoring the interaction carefully, even joining in her/himself just to make sure everyone is all lovey and tender and no one gets squished. I mean, wouldn't that defeat the purpose of the hug in the first place?
