Her (in a not too rude but totally serious way): "Mom, are you mental?"
Me: "Quite possibly. Why?"
Her: Why did you put this in my lunch yesterday?"
Me: "Um, because the oranges I tried to make into jack-o-laterns with a sharpie didn't turn out as well."
Her: "OMG, you are soooo embarrassing me. I'm not a little kid! Save it for your blog next time, please?!"
