Just... write a breakup story. Whatever fandom you want. Whatever kind of breakup you want. Whatever. And then we could get 50 of them and host them (I'd donate some frowl space) somewhere.
And it could be awesome.
Or it could be lame. Um... so let me know. (And if this does turn out to be something enough of you'd be interested in, you can all feel free to post it elsewhere in your individual fandoms.)
