I COB'd into a local sorority after dropping out of formal rush. It was their first-ever rush, held immediately following FR, so one of the rho chi's from FR stayed deaffiliated an extra week to act as "our rho chi". (Thankfully, not the evil hell-b!tch who was my PX from formal rush

)
We rushees (

) were told to gather at a particular location on bid day. The PX took each of us one by one into a side corridor and told us whether we'd gotten a bid or not. I was the first to arrive, so I was the first to find out... YES! So I was the first new member at the bid day party.
We also had to rank the sisters in order of how much we wanted each of them as our big sister, so I got my big that day too.
I was the first in my family to go greek. When I called my parents to give them the good news, my dad said "You did WHAT?!?!" (he's anti-greek as I then found out

) but my mom was so thrilled.
