Um, is Margo supposed to be acting like an insane person or is this the curse of Diana Devine? Who takes a shower at 2 AM? Even if you need to take a shower at 2 AM, you just pass out in whatever state of grossness you are currently in. Maybe you wash your face/brush your teeth. If you feel like it.
The apparent timeline of this strip indicates that Tommie and Lu Ann were out on the town until sometime after 2 AM? NONE OF THIS MAKES SENSE!
