6. Anyone riding the Green Line to a Red Sox game If Dante was alive today and writing The Inferno while living in Boston, the Green Line during Red Sox season would be his worst Circle of Hell.
5. "Hey, look at me, I'm wearing a giant backpack in the middle of a crowded train!" guy And I love to turn around. And around. And around. I hope I don't miss my flight to the Netherlands.
4. Dude who waits until the doors have been open for half an hour before jumping up from the middle of the car to scamper off the train Listen, man, we get that you're totally enthralled with The Cuckoo's Calling (spoiler alert: it's the same woman who wrote Harry Potter!), but the train's been stopped for, like, ever. Pay attention.
3. Guys who refuse to offer their seats to the elderly, infirm, pregnant, etc. Have we really reached a point in civilization where quickly glancing down at your iPhone and pretending not to see the pregnant woman with a broken leg hobbling in on crutches has replaced any semblance of chivalry? Really? Are you, per chance, also going to the Red Sox game?
