On The Big Bang Theory, an American television show about a group of physicists and the girl next door, two of the main characters share an apartment together. In order to ensure that things run smoothly from the beginning one of the roommates drafts a roommate agreement that outlines all of the rules by which the two characters will abide.
Additionally, anytime there is a change in the characters’ status (for example, if one of them starts dating), this roommate will write a modified version of the agreement to accommodate the new arrangement.
However, the second roommate hates having a fixed list of rules, and rather than being a way to solve disputes, the roommate agreement actually becomes the source of many arguments.
