Basically a roundabout way of asking: How much do people really care about you?
I know I could vanish for like 48 hours and my parents and older brother probably wouldn’t even want to look for me (I’m around 18-25, not a minor so they have no legal responsibilities). Nobody in the world cares about me. I mean they already told me that in my face that if I went missing, they won’t care.
I think people would notice early (work would definitely be the first to know), but would take a while to actually report something.
I think it’s pretty universal; people don’t want to make a fuss or be a bother… like it would be embarrassing or something to report someone missing for not showing up to work, or missing a gym session. Not to mention the not-so-missing will probably feel quite upset about getting reported missing because they took an unprompted nap or lost their phone.
It’s not strange for adults to not answer their phone, and in NPF-circles it’s even less strange for someone to go into social hibernation with very little warning.
Unfortunately this will lead to (single household) adults being missing for longer before people get worried enough to actually tell someone, and then they’ll try to get in touch with other friends or family before the actual police.
