Hi, folks! There's a weird dynamic in here with some of the answers, and i don't love it: several folks have validated the Asker's right to say no, but then gone on to point out that she could in fact say yes instead. This seems to me to be a kind of low-key interrogation of the premise of the question.
I'm leaving all of those up for now, but please note that "well, you could say yes" is not an answer to the question "how can i say no in a way that won't have negative effects on me/my property".
Separately, one comment deleted for not even attempting to answer the question.
