I can understand where he comes from. I, too, have trouble with Snape/Hermione, largely because of the age issue. And I don't like slash. So generally, that leaves a small pool to pick from -- sometimes the dreaded OC. There are quite a few good stories at Occlumency at Sycophant Hex (the non-Hermione Snape fanfic), although I haven't had time to read fanfic in YEARS, so I'm not exactly up-to-date on good stories.

(Maybe he would enjoy The Sempra Deck by our own TeddyRadiator! ;) )
