Who are you telling?

Who are you telling?

I know exactly what you're talking about; you don't need to explain that to me. A: "Some days I'm just so exhausted by the kids that I can barely keep my eyes open." B: "Hey, who are you telling? You think I'm not worn out looking after my three rug rats?" A: "That was a pretty dumb mistake, Jerry." B: "Who are you telling? I'm going to be paying for it for years to come!"
