I'm currently on the bus and the girl sitting next to me has continually hit me with her elbows, poked me with the edges of her economics textbook, and kicked me. I want to say, there is an arm rest here that deliniates the boundaries of your seat. Yes, you may fight for the rights of the arm rest, but you may not cross to the other side. This also goes for planes, trains, and movie theaters. Respect the arm rest!
