yeah, that is such a bummer. Put up a sign of some sort in the area where she's doing it maybe? You could get creative!
Or if there is a bunch of you annoyed by it, someone could turn on a radio really loudly when she starts in.
My new neighbor likes to spend all day out on her deck yakking aimlessly on her cell phone. She goes on hour after hour. She's not hollering, but her voice is one of those that strongly carries over distances. She's about 40 yards from me, but I can hear every word as though she were standing next to me. I swear she has no idea how her voice carries. I cough, I sigh, I bang shovels and make noise so she knows I'm
right there gardening or trying to relax in my yard. She's clueless. I'm a captive prisoner to her boring endless yakfests.
Once my DH started saying "BLAH BLAH BLAH BLAH
BLAH!!!" really loudly, but she still didn't 'get it'.

lol! We'll see how the situation progresses this summer.
