No parent should ever have to say they waiting on child support. Or they (or children) haven't talk to that parent (in over a few days unless the missing parent is dead or in military. There is skype). And even if the parent is a dead beat, no children should ever hear anything bad about that parent from the parent/grandparents that are present. It's just foul. If you gotta talk about them make sure the children aren't around. Because, I tell you what, children grow up wondering what you think of them, who is part of that parent. Let them from their own opinion.
