Your sister's roommate was recently married and now has a full-time job. before that time, she partied a lot and was pretty crazy, wild, and engaged in quite a bit of risky behavior. according to osgood, because of your sister's roommate's new role transition, she is engaging much less in

unstructured socialization

Explanation:

Unstructured socialization refers to a situation in which the individual puts himself in less conservative situations that are contrary to the ideals of traditional society. These situations pose a risk to the individuals involved because they are dangerous situations or things that can create problems such as the crazy and wild behavior your sister's roommate had before getting married. For this reason, we can conclude that if the roommate has abandoned her risky behavior, she is much less involved in unstructured socialization.
