It's somewhat known around here that I currently make a living helping folks to buy, sell and rent housing. In my city, as in many, there are far more dog owners than there are dog-friendly apartments. There are also many large families who need 3+ bedroom apartments, while the housing stock breakdown favors units with 2 beds or fewer.
This seemingly random story will make sense in a moment.
If I'm trying to find housing for a couple with no pets, I will not put them in a dog-friendly unit, and I will not put them in an apartment with more than 2 bedrooms. I don't care if they need to work from home, I don't care if they have a lot of guests come to visit. Because I know if I waste that dog-friendly 4 bedroom apartment on the pet-free couple my next clients will be a family with five kids and a puppy. Some housing resources are simply too scarce to waste on people who "want" them for part time use over people who actually need them in order to keep everyone in the real house instead of the doghouse. (Pun utterly intentional.)
Theatre jobs are also scarce, MRE-eligible ones moreso. Your friend is much like my example couple above - the job isn't a perfect fit and I guarantee there is someone out there who really needs those 10 weeks. It would be a disservice to the community to take the job. I know self-preservation comes into it here and a good freelancer should watch out for their own career above all, but still, there are always several folks in the "right person for the gig" club and schedule conflicts mean you can't join.
In addition, there's the "dead grandma" factor here. There was a kid in my high school class who tended to skip a LOT. His excuses of illness got pretty worn out so he shifted to saying that assorted family members had died. He was on his sixth dead grandmother before the school figured it out. I'm of the mind that MRE, like funerals, should be used only in case of emergency when they actually occur so one doesn't get the reputation for skipping out on gigs.
So yeah, either tell the truth and see if you're the
sine qua non of the director's
mise en scene, or take a pass on the gig altogether. Perhaps with a light scolding to the company for waiting too long to book a hot commodity.
