Toasted Cake 111: The Roommate Situation by Josh Roseman
Toasted Cake 111! In which we consider Sh'pach.
Other than the pheromones, and the fact that I now have to wear a breathing mask when I sleep so that I can actually get some sleep, there's only one thing that drives me crazy about Mrf.
Josh Roseman (not the trombonist; the other one) has had fiction published in Asimov's, Escape Pod, a Crossed Genres anthology, and several other places. He's a member of SFWA and a graduate of Taos Toolbox, and is probably at this very moment either writing or complaining about not writing.
