I also pointed out the deadly nightshade they were growing.  She replied, 
"no! that's bleeding heart!" sigh.

Hi Kitty,

All top growth, and because thistle is so susceptible you can just use the 
cheap 5% vinegar found in grocery stores.  

This ARS article discusses it in-depth:

   
https://www.ars.usda.gov/news-events/news/research-news/2002/spray-weeds-with-vinegar/

Because 5% doesn't affect much else, you could probably spray the whole area 
with vinegar and eliminate most of the thistle.

P.S.  Your neighbors sound weird.  :)
