1. Leave a seat between.
Never sit next to a person in a lecture hall unless every other seat has been taken. Always avoid your classmates' three-foot personal space bubble unless you want to play an awkward game of "who gets the armrest."
2. Bike trumps walking, but skateboard beats bike.
It's the rock-paper-scissors of who gets control of the sidewalk.
3. Laptop screens are fair game.
If the person in front of you is having a deep personal IM conversation on their 17-inch laptop screen, feel free to read it. It's fair game.
4. If you stare down at your cell phone, magazine or iPod, you're invisible.
The salespeople on campus won't bother you, and people walking or biking toward you will be forced to swerve.
5. Text message relationships are fine.
Even though you haven't heard your friend's actual voice in over two months, you know exactly how her classes are going this semester. She texts you during all of them.
