I vote absentee, as do most of the people I know, and after 2020, none of us are mailing our ballot back. We are taking them to the in-person voting areas and dropping them off with staff.
In 2020, there were reports of ballots being dumped, and so far there have been reports of drop boxes set on fire and stuff… it’s hard to trust, because of republican stooges seeding chaos, and enough of a pain in the ass to fix if it gets messed up that we aren’t taking chances.
Edit: seeing to seeding
Food related patterns would be pretty strong indicators for me as well, I think.
I only eat after 4pm (sometimes only from 6-10 or so) and people comment when I actually eat earlier than that, especially breakfast. I almost never use condiments or salt (I’m on a very low sodium diet and have been most of my life; I don’t use salt outside of baking, and that’s half salt). Give my dopple unsalted fries and you’ll know right away.
Drinks would work well for me as well - coffee made a very specific way, or room temp water, mostly (I actively dislike cold and hot water).
