She may not mind. I agree with what has been recommended talk to her and if that does not work out get something to block them But remember leaves are garden gold.
I have a lot of leaves but I would have probably have been over there asking her if she mind if I gathered them up for my garden. I gather probably 30 bags a week of leaves and pine needles in the fall and still have so many leaves when it rains and snow comes that I cannot get out of the yard.
