I think driving 18 hours with anyone (even your best friend) could be murderous. Hell, even after 2 hours of driving with mine, I'm ready to slap him silly if it wasn't for reaching our destination and starting our "mission." hehe
last summer term, we had to do a group debate over the euthanasia issue, and coincidentally, I was finishing up Chuck Palahniuk's Choke. At first it started with most of the class against it, but after our debate (and all of the research done for it) 90% of those had a change of heart. It's funny how politically liberal people really are when they openly say they're conservative.
