Of course, as "fun" or therapeutic as these conversations may seem at the time, they almost always result, later, in your feeling super crummy. You get on the subway and you stand against the door instead of sitting in one of the open seats. You have a momentary paranoid flash of Rachel divulging to Emily all the awful things you said over a bottle of wine on some future Friday night, and you feel nauseous. Most of the time, Emily's great. You love Emily. And if you and Rachel fell into a Emily trash-talking conversation that easily, aren't the chances pretty good that the two of them have had a similar conversation about you at some point?
You get off the subway and immediately text Emily some stupid forced joke and ask if she's free for dinner later that week.
