mrstraci,
Being new to greekdom I've seen some Sorors who want you to greet them in a certain way and then on the other hand if you don't know for sure you are either insulting someone or exposing a fraud. I've learned to take the "bumps in the road" and learn from them. I had the same thing happen to me at my school which is also BGLO lacking but this Soror was more than excited to see that someone recognized what she stood for.
