Have no idea what to make of your first few statements...but that's okay. It doesn't sound like something I want to know.
About bid day... Expect a party-like atmosphere. What happens at Texas Tech is this:
Ladies who get bids open their envelopes and discover which house they got.
Your bid card will probably read something like:
"Rhonda Rushee is cordially invited to become a member of XYZ Sorority."
It will likely be a variation of the above.
After reading their bid cards, new members board a charter bus to their new Greek home. All the current sorority members are assembled on the lawns in front of their houses. As the girls get off the buses there is cheering, excited screaming, happy tears, hugs...
Each sorority gives its new members a Bid Day shirt, which the girls change into.
We have a professional photographer on hand who takes tons and tons of photos. The new member class together, then the whole chapter, then the various new member classes, then Big/Lil Sisses, friends, fun pictures, silly pictures, serious pictures, you name it!
Then we usually have a big sisterhood party planned. For years the mayor of Lubbock hosted us at her home for a big reception (she's an Alpha Phi). More recently we've had pool parties, Barbecues, etc. This year we got 61 beautiful new members. We took them to a huge Bid Day Bash at a ranch outside of town. There were alums there too, which was awesome. We had a great time.
At the Bid Day event, dinner or snacks will be served, there is singing (we teach the new members some fun Alpha Phi songs), sisterhood events, games, and just plain fun!!
Our Bid Day events are usually casual dress (it is too hot in West Texas in August to expect more than shorts or casual khakis--especially when the events are outside!).
In short, expect fun, getting to know your new sisters and learning about your new sorority home.
Every School is Different... but expect fun, fun, fun!!!
Oh, I forgot! Our new members each get a Bear Buddy, who is a special friend to them during their first few weeks in Alpha Phi. Each week our new members get a new Bear Buddy, who is like a Big Sis. Bear Buddies call the new member, and give her lots of gifts and Alpha Phi paraphanalia. Over something like five weeks, each new member will have a different Bear Buddy, one of whom will eventually be revealed to be her Big Sis during Big Sis Discovery. Most sororities have a Big/Lil-type of program, but it varies from group to group.
Anyway, I hope this helped. Here's hoping you will find your sorority home tomorrow. Best wishes to you!
Cheers!
