If its just seeing the house, well its still gonna be there and she is still gonna see it every time she drives by.
I think the city should demolish the house so this single resident can be appeased.
We've had pain and trauma in our house over the years and for about a year, we seriously considered moving just because it was so painful to live here... but we stayed and I'm glad and the place is filling up again with good memories. We all take our pain with us wherever we go.
