If she had had any sort of gall, if Umbridge hadn't already pretty much overruled her and nearly threatened her own business; she'd just have ignored the damn decree. Luckily the business was run on her own funds, she was the only employee, the woman could have fun running through what little she had; potion ingredients, schedules. It said nothing about customers or clients- which in this instance she would place under her wards as, and of course, if Umbridge wanted more, demanded more, she could merely feign that the request of such information was not requested, and no harm done.
The escalation of decrees, however, did worry her. Every day another came out Hestia began to wonder her prior decision not to leave the country... With Death Eaters and now Umbridge? Her children hardly needed that sort of environment, she didn't want them to have that sort of environment.
Where did she go, though? She had a terrifying image in her head of just constantly being on the run, trying to escape and the war only a step behind her... It was only one more reason why she sent off her paperwork to the Bitch, she couldn't be a coward, even if she desperately wanted to be.
