That's it for me, too, non-tattooed person that I am. I'm not fundamentally against tattoos: I just can't think of anything that I'm sure I'll want to subscribe to forever. I appreciate Daniel Weber's comment drawing an analogy with marriage and faith, but pace Daniel, we change and evolve within those. Unless there's something about tattoos I don't understand, they do not change. They always say the same thing.
I don't have any bumper stickers on my car, either.
