What is the significance of "Wednesday Nights" in the memoir, We Need to Hang Out?

This is the term for both an event and a place - specifically, a regular gathering hosted by an acquaintance of the author. The gathering, in the author's understanding and in his acquaintance's intention, was an opportunity for friends to gather and connect. As both an event and the site of that event (i.e., a place), it defines a model that the author seeks to emulate throughout his search for friendship as a counter to the dangers of loneliness.
