For Patricia, no, none of that applies. I also can't buy them because they don't appear in the shop or the stores on the map. Is this a forgotten objective in the game, since I can't complete it? For Liz, you can talk to her and ask her questions at 8 PM, but it often doesn't work because her mood decreases since she doesn't seem to agree with the answers given.
And for the neighbors, I'll try this solution :)
