We’ve got a guest staying with us right now who’s here for an internship in special effects makeup and design. Her project while she’s here is basically to design and create a model alien.
You can’t imagine the mess it’s been causing.
There are knives and clippings all over her bedroom floor. The back porch is covered with foam bits from when she decided to dremel her model one evening. We’ve had plaster heads in the oven, and silicon masks in the shower.
Hosting her has indeed been quite an adventure. And personally, I don’t mind the mess. But if such goings-on will bother you, make sure you make that very clear in your house rules! If you’ve made it clear from the beginning that such behavior is not allowed, it will be much easier to address a violation later on.
