Short Story Plot?

I've been working on this one for a while, but you can have it if you want. Not all the kinks are worked out. Your main character switches from scene to scene. It's a small family, just the mother, the father, the teenage son, and a two year old girl. They are your basic family. On the surface they seem normal. Cheery and have their own personalities. The trick is, none of them can be taken at face value. None of them are truely happy. Yes, including the two year old. It can actually be pretty interesting to come up with the psychological mood of a baby. Trust me. They are all deeply depressed, and they don't know what to do about it except pretend everything's normal. They're empty shells, and they don't feel like they are really alive. Like they are just there for no reason at all. Depressing yes, but much can be done with this. They each dwell on the one thing in their life they would have done differently, or what somebody else should have done differently. You see their ups and downs. You feel for them. You cry when they cry. You hurt when they hurt. Make sure they each have some sort of humor. They all think that they are the only ones who have a problem, and so they don't turn to each other, which might be the only thing that can save them. The story can either end in a m enlightenment or really thoughtful, leaving you to draw your own conclusions. I hope you like it. It might not make much sense on here, but it's clear as a bell in my head, playing it there like a tv show. Hope you can make it your own and get that picture too. Good luck on your paper wether you use this or not.
