help me out here [View all]

i have a neighbor that has terminal cancer. we were friends for a very long time, but had a big fight a couple of years ago over my farm. long story.
now i am getting a lot of flack around the hood over my roosters. this person is directly across the alley from me. we recently talked, sort of, and she insists that the sound is so loud that it is driving her crazy.
folks who live closer, including me, just dont feel like it is. i can barely hear them in my house, and they are in my back yard. sympathy for this woman drives a couple of the other neighbors.

here is my question- can advanced cancer cause acute hearing sensitivity?
i have known other people who had strange things happen in their brains as the disease advanced, including stark personality changes.
could this be part of the problem?
i am not going to "use" this in my fight, i just want to know if this could be what has happened to my formerly dear friend. maybe this could help me repair some of the damage to our friendship before it is to late.
is there anything that might help, if this is the case? i have offered to foot the bill for sound deadening window treatments to at least let people who say they are affected get a better night's sleep. this got smacked down as attempting to shirk my problem, but it is sincere. i have sleep trouble myself and there are a lot of other noises here.

an advice for me?
