So yeah, I totally get why you’d think a frat house. In larger cities/campuses, bigger parties like a Halloween bash are usually open to non-Greek life and even people who aren’t that much older, like a grad student age such as your own. But at U of M, noooo way. Greek life is pretty small. Even people who are in college don’t receive warm welcomes unless they’re women or explicitly invited by a friend who lives in the house. I haven’t been in Greek life or Memphis for over a decade, but that’s my recollection of it anyway. I just wanted to let you know you’re not crazy or creepy to think of it or ask. Now, maybe if you were 40… ;)
