Our chapter sings "The Legacy Song" to the bride at the reception, However, sisters who came to mine were too embarrassed to sing it in front of everyone so they sang it in the bathroom

while I was changing to leave. We were ROTFL and suddenly, we heard this little voice come out of a stall saying, "What are y'all DOING?" (non-Greek bridesmaid, we'd thought we were alone)
The Chi Os at Mississippi State had this garter that each girl wore to her wedding and she would sew a ribbon to it with her name and wedding date and send it back. It had about 2 billion ribbons on it and I don't know how it stayed up at that weight or how they always got people to return it!
