I think this is crazy. She lied to you, made you all complicit, and now, it's threatening your business. But you want to let her get away with it allowing her to endanger the company.

Well, you want some tea, Shelly? Everyone is pretending to be younger. We dye our hair, we whiten our teeth, we wear moisturizing face masks that make us look like serial killers, and we squeeze our widening hips into Spanx because the most important thing to be in the whole goddamn world is 27.
