1. She taught you how to be a sorority woman. Joining a chapter can be a mix of excitement and terror because you are about to set foot into the unknown. Just as your parents taught you how to function in society, your big shows you the norms of being a sorority woman. She will be there to help you grow into the classy lady you are and branch out in this new environment. She will answer all of your questions so you don't have to be the new member who constantly posts on the chapter Facebook page asking for help.
2. You have a partner in crime. No matter what you want to do, you have someone to do it with. Whether it is a community service project, catching up on a TV show, or you just want to get dollar scoop ice cream, your big will be there to accompany you. Maybe dancing around on raised surfaces is more your thing, in which case, she will probably be right next to you -- or helping you down.
3. She has all the answers. Transitioning to college can be difficult, but your big is your older and wiser mentor. Even if she hasn't personally gone to that club or event you want to attend, she probably knows someone who has and can help you out! If you are lucky, she may even be able to tutor you in that class you are struggling with.
4. She is on your side. She will always be there to listen to you and talk things out. Even if you are wrong, she will defend you and support whatever you do -- which is a very underrated trait in my opinion.
5. She is your big for life. Eventually, you will reach that point in college when your big graduates -- a.k.a. the worst day of your life. Luckily, I can tell you from personal experience that she will be there for you long after she is gone, no matter what separates you. My sorority's house mom had weekly phone conversations with her big and her little, up until the day she died.
6. She loves you. We all have our extremely unlovable days, but especially then, your big loves you. Everything you accomplish excites her. She loves making crafts for you even if crafting isn't her thing, and she is one of the best friends you could possibly have because you are, basically, her child.
7. She has taken you under her wing. Who knows where we would be without our bigs? And that is part of what makes them so special. As littles, we are so obsessed with our bigs, and look up to them, so it helps that they adore us, too!
