You asked, so I’ve just gotta give you the straight goods.
1) This ain’t no Disco!
This ain’t no party. This ain’t no foolin’ around! Everyone is there to do his or her best work. For sure it’s fun to see your friends and to socialize a bit, but please remember that your boisterousness can affect someone else’s ability to focus. Talking on your cell phone is distracting to others. Your loud guffawing can be heard in the studio where actors are auditioning, and picked up in the sound of their audition. Not cool. So be happy but chill please.
