I'll admit this is sheer nosiness on my part. I'm not really on speakers with the family so can't ask directly (although I may be able to find out via another neighbour at some point) It's such an odd situation I can't work out what's going on but I bet someone on here will be able to offer a plausible explanation.
We live in a typical suburban street, all homeowners. Family in question have (primary) school age kids, have lived here for about 10 years. I noticed about a fortnight ago that their car wasn't there overnight. No big deal, I assumed they were away on a break. But the next day the car was back, for an hour or two, and then gone again until the following day. I thought maybe one of the parents was working nights, but the house is definitely unoccupied, none of them are there at other times just this hour or so daily. At those times they're all here too and all seem to be in good health so that's not the reason.
I thought maybe some sort of damage to the house had happened that might mean they needed to move out (this happened to a relative who had subsidence for example) but it didn't make sense they'd come back daily, I know my relative had to move out completely and everything was put in storage.
They could be doing works to the house, but there's been no one else here (and as we're terraced we'd definitely hear any works).
I thought they might have moved out to rent it, but all their stuff still seems to be there (kids toys still in garden etc). I can't think of anything else - and I guess I'm interested because if they have moved I'm wondering if they're selling, if we'll get new neighbours etc.
