I remember once reading a short short story about grown-up Calvin having survived some post-apocalyptic craziness, losing his true love Susie, and then getting sent back to being a 6 year old. I recall finding it via a link here at Hatrack but I've searched (and searched . . .) and haven't found it, thus prompting my return from lurker status.
Anyone else remember this story? Where it's located online?
