Sorority Recruitment is a big deal in the life of a college girl. It's a big deal trying to find your home away from home. Freshman year of college is an intimidating time, so finding that home away from home is even more important. Sorority Recruitment seems like a foreign concept to some people, but honestly, it's very similar to Hogwarts students being sorted into houses at Hogwarts.
"Houses will be something like your family"
According to Professor McGonagall in the Sorcerors Stone, she tells Harry and his fellow first years that their houses will be like 'family." This is very similar in sorority recruitment because you are literally given a family after joining. You get a big, grandbig, maybe a twin, an aunt, greatgrandbig, cousins and more. So just like the Hogwarts students, the house you get is also like your family.
It's literally a house.
During recruitment, the different sororities are called "Houses." Girls during recruitment will say something along the lines of "I got invited back to this house..." or "I cut from this house..." It's literally the exact same at Hogwarts! Basically, the four groups are called Houses, just like the different sororities during recruitment.
It's about values.
The National Panhellenic Council has the different sororities pick their new members based on values and the new members pick where they want to be based on vales. Just like at Hogwarts the different students are sorted into the four houses based on their values. For example, Ravenclaw's core value is wisdom. Whereas, Gryffindor's main value is bravery.
Members live in and with their houses.
In the Harry Potter books and movies, you see that the Hufflepuffs live with the Hufflepuffs, the Slytherins live with the Slytherins, etc. In Greek life, some houses require their members to spend one year (sometimes two) in sorority housing, whether that be in the sorority dorms or in the sorority house itself. This is exactly the Hogwarts students living with each other.
Members eat with their houses.
If you're lucky (like me) your sorority house comes with a meal plan. Now the dining room at my house isn't nearly as fancy as the Great Hall of Hogwarts, but the members of sororities that do have meal plans can eat together. Eating together creates a certain bond between people. The students of Hogwarts eat together with their respected houses, just like sorority girls do with their sorority sisters.
Houses play sports against each other.
Intramurals are a huge part of Greek life! This is the same at Hogwarts. Imagine Hogwarts without Quidditch... That's right you can't! The same goes with intramurals and Greek life. Sorority girls play sports just against the other sororities, just like the Hogwarts house Quidditch teams play against each other.
In your house, you face trials and victories together.
No matter what house you are sorted in at Hogwarts or whatever house is written on a bid card. This house is there when you are getting ready for a date with that boy you have been wanting to ask you out or whenever he broke your heart. Your house is there for you. Your house is there when you are trying to find a job, make a bad grade on a test and whatever else may come your way. No matter if you're at a University and a member of Greek life or a witch at Hogwarts your House, is not only your house. It's your home.
