I think oftentimes choosing a sorority is a lot like finding your husband. People say you will just know when the right person comes along. I think that is often (but not always!) the case with choosing a sorority. At some point in the process you just KNOW this is the place for you. You might not even be able to explain it to someone else, but something just clicks.
When did you know that "ABC" was the place for you? Was it a song? Something someone said? The first moment you walked in the door? Something done in the pref ceremony? Or was it later after you opened your bid card? Joined your new sisters at the house?
What sealed the deal for you?
