Why not just save your money that you have to pay to join (i think).
Fraternities/Sororities= Buying friends cause you cant make any on your own....
While this statement will piss many here off, I completely agree. Frats seemed like a "cult" to me. Who wants to be forced to associate and live with dudes that you may not choose as friends? One of my friends from the dorm freshman year ended up joining a frat mentioned above. Long story short, he turned into a tool.
Going further, living there is expensive, you're roped into a bunch of silly meetings and/or "community activiities", plus you will be forced to live under the "house rules". Why do that?
Finally and most importantly, most sorority gals are not all they are cracked up to be. At the school I went to, there was one house that was known to have hot chicks. The rest of the sorority gals that I knew were in generally in the 4-6 range (on a scale of 1-10).
Meet people in the dorms etc. and then move into a house with them. You can have more parties without all the bullshit strings and rules.
