How long it keeps. But as long as it’s not meat or dairy produce, it’ll be a “best before” not a “use by” date, and most stuff is usable long after its best before date. Those crumpets will be fine for at least a week, if you keep them in an airtight container or ziplock bag after opening. After that, they might be a bit stale, but still edible; warm them up nd put a bit of butter on, that’ll soften them up nicely.
I’m NT (I think) but I resonate with this. I have an online friend that I’ve known since about 2005; he’s autistic, though neither of us knew that at the time (late diagnosis). Anyway, around 2014 or so, he just… disappeared. He was going through some nasty relatioship issues so I figured he needed time to get things sorted, or was maybe depressed (I have experience of that and I know the last thing I want to do when I’m depressed is talk to people). Anyway… in 2021, he messaged me again out of the blue, and we literaly did just pick up right where we left off, and its great. We immediately went back to chatting nearly every day, and still do. And he’s now happily divorced.
No. Unless your meatballs are made of ground bacon instead of beef. Pineapple goes well with bacon, and fish, because the sweetness balances the saltiness of the meat. But beef isnt salty like that.
