As sororities and fraternities complete their fall semester rush and start the pledging process, current sisters and brothers reach out to senior members to become "bigs" to the new members, also known as "littles." In Greek organizations, bigs act as a mentor and are a constant presence to their littles throughout the semester.

"Everyone thinks that sororities are always so close, but sometimes that's not always the case and you get frustrated," said junior Brittany Woods, president of Delta Kappa Sigma. "It's always good to know that there's always someone there who understands, will listen to you and will always be there.

Woods is a big to fellow junior Brandi Brush, a transfer from Cal Poly Ponoma.

"[Bigs] are really good to help you get used to going to school and sorority at the same time, so that it doesn't get too overwhelming for you," said Brush.

Although Brush hasn't been a big yet, she hopes she will become one for the first time this semester. Meanwhile, Woods said she used her big sister as an example in mentoring Brush.

"My big sister really pushed me not just in my sorority, but also in life and in my education," she said. "She was one of the girls who started our sorority, so she was just really focused."

Woods said that her big sister still keeps in touch with her even though she graduated, and that the big and little relationship extends outside time in a sorority. There's also a family-like hierarchy between sisters.

"My big is Brandi's grandbig, and furthermore, if a big has more than one little, those littles are twins," she said. "Some people get way more into it and find aunts and weird things like that, but for the most part, there's little, big, grandbig, and twin."
