If you saw last night's episode, you would understand all the mad faces (well, maybe...let me explain)

Why is it that Joan cannot make up her mind? She gets on my nerves with her little temper tantrums, especially her getting so angry with Lynn about not mailing her fashion letter 10 years ago in college. I mean, if she was that worried about hearing from the fashion school, why didn't she call them after not hearing from them for a couple of weeks? It makes no sense. She's really gettin on my nerves. Then when she got that promotion, she refused it, but lied to lynn saying she was happy, knowin she wasn't. I bet she'll be right back at that law firm next week. We'll see.
