Oh wow, I was convinced Maria was going to keep dancing around the subject. She'd been phrasing everything in terms of "surely anyone would..." and "I'd be a fool not to..."

Honestly, I'm less surprised by the donation (it doesn't actually get the door open and she knows it). What surprises me is the directness of her wording here. There's a tiny amount of wiggle room, but anything more precise wouldn't sound natural.
