I used to host a movie night with my friends after college on Fridays, which was the highlight of everyone's week. It became a tight group of friends.
We had set of rules. First person in the door got to pick 3 titles, and the group voted on what we watched. I got 1 veto a month (because one person in the group liked to show up early and had poor taste in movies).
Some weeks we had themes to mix it up and keep it fresh. Holidays would warrant a theme, or someone's birthday.
We also had communal food and drinks. People would leave their snacks and drinks and mixers at my place, which would only get used on movie night.
I reflect fondly on those movie nights and that group of friends, and wanted Troy and his friends to start to experience something similar. Because the series got compressed, we just had Cheryl join a weekly roommate tradition, which made for more comedic opportunities.
