I don't really care if she reads comics. She doesn't ask me to read Diana Gabaldon books, I don't ask her to read comics. She says I'll probably like them just like I say she'll probably like Y: the Last Man but that's pretty much it. Neither of us care that we have our own things. We're not zealots who need to convert everyone to our cause. It's kind of sad to think you can only love a mirror image of yourself...why would you do that?
On an interesting note she just ordered what I think is probably the most original combination of genres I've seen in a long time: Undead and Unwed. Vampires and chic lit. Kudos!
