How long could you be

[Imafairy]

Sorry - quotes are only because I can't think of what else to call it.
I first thought of this when I heard about that poor woman and her three kids in Manchester who may have been dead for up to 4 weeks before anyone noticed they were missing, and was reminded of it again this evening when I heard the husband was arrested.
I just can't comprehend how no-one noticed that they were missing or not responding to communication. My family all lives in Ireland, yet I have contact with at least one of them on a daily basis. My DH's family on the other hand live about an hour away, yet they could go regularly for a week without talking (which I find strange) but any longer than a week and even they would have alarm bells ringing.
So I guess my question is, without it meaning to be too morbid, how long would it be before someone noticed something was amiss chez vous?

Sorry title was 'How long could you be "un-contactable"' but I'm having a fat-finger evening!!!!

hopefully only a day, as if dh is working away he calls every day at least twice a day, and has said if he couldn't get hold of me, he'd ring friends/my parents etc to check I was ok.....however if he were to bump me off, it could be a few days before you lot reported me missing or people realised I wasn't answering text's n calls etc.....

Not long , I have a neighbour who lives in her window! Usually see My Mam a least once a day, know most of the neighbours and usually speak to at least one of my friends every day, and think work would notice even if it was just the kid I support!

DP (who lives 200 miles away) would notice and worry that i wasn't replying to texts after a few hours. But wouldn't act on it for a day or two probably.
My mum wouldn't notice for a week or two.
Everyone else... weeks.

Honestly? An hour max
