Catholic University has many rules and regulations. After a certain hour, students must be on their own floor of their own residence halls. In addition to this rule, students must refrain from making an obscene amount of noise, abstain from having alcohol or alcohol memorabilia in their rooms, and avoid the use of surge protectors.
But enforcement is a whole other issue. RAs wield the ultimate power. Yes, there are RAs who will go above and beyond the call of duty to make sure students get caught, but most follow the simple philosophy: "Don't let me catch you." Most RAs give students a careful but comfortable margin of error so they can enjoy their college years. The most common offense is underage drinking, and it's hard to stay quiet for long in a room full of drunk people, but as long as students practice decorum, they can achieve a harmonious balance between appeasing the higher-ups and living up the best years of their lives. It's a careful but achievable balancing act.
