I also met someone I worked with back in San Francisco. We actually didn't talk to each other because I didn't recognize her until AFTER her audition was over while I was waiting. I saw her face and I was thought to myself, "heeeyyy..... that's........ YEAAAA". I worked with her as a background in the Colbie Calliat video which you can see in my acting work tab here on my website.
It happened at the very end as she was leaving and I was entering to do my audition so I wasn't even able to ask her if she was who she was. Oh well. Nice to see she's doing what all aspiring actors are doing. Chasing that goal.
