We auditioned for a role, short film, unpaid, 5 hours drive away - as we usually do to get experience - she didn't get it but got a background role. Normally we would take it but that same weekend is her BFF bday so I am not going to ask to move stuff around or create a hassle for us just for the background role. How do we professionally turn this down without looking like we are sore losers (we are not).
