Not Quiet Yet

Last night I was at Janissa's practicing for the Saturday gig.  I know I'm supposed to be silent buy I need this money to keep my phone on. After this I will be quiet.  I won't go to any open mics or auditions for two weeks like the Dr said. I got an unexpected call yesterday evening to come to a job fair for vets.  Im going mostly because they are giving $25 gift card for attending.  Wonder if I can do a costume change and get away with two?
