For "social" I read "mixer". *puts on dunce cap*
I'm still curious as to why the school was setting up these socials - regardless of whether they intended to set up a mixer with two opposite-sex groups or a social event with two same-sex groups.
The confusion between AEPi and AEPhi strikes a particular chord with me (as an AEPhi) ... when we first became an AEPhi colony, random people kept coming up to us and asking when AEPi had gone coed (fraternities going coed at my school is not without precedent), or were we some kind of little sister group for AEPi, or what. I've said it before ... you'd think that people at arguably the top science and engineering school in the world would be able to tell the difference between pi and phi.
But I digress.
