Go on, break another one

The part of the movie that I think sums it best is the part when the four characters stop at a Indian Reservation gift-shop type store and just start breaking and shattering everything in the store. As Columbus said afterwards, "Sometimes Tallahassee is right, you gotta enjoy the little things...even if that means destroying a whole lot of little things." 

For me this scene symbolizes two main themes we see in the movie. First, the obvious connection I made was that this raging act of aggression was the characters' outlet to release their frustration with living in Zombieland: always on the run without a home, having to watch their backs constantly, the focus on survival...etc. Second, I also perceived the experience as a therapeutical bonding session between them. Somehow, by smashing all sorts of delicate glass structures, Tallahassee, Columbus, Wichita, and Little Rock were able to get over their animosity towards each other and experience something fun together. Afterwards we see 15 second clips of how they got along pretty comfortably in the car as if they had known each other forever. 

In recap, this scene symbolizes the struggles of Zombieland and ironically enough, the camaraderie of new friends made in Zombieland. For these four characters, the road trip brought them closer. So what would the definition of a road trip be for the movie Zombieland?
