This is more a WWYD rather than an AIBU.
We've lived next door to some pleasant people for 12 years. We always speak when we see them, they always speak when they see us, sometimes we have a good old chat. They are nice neighbours.
They both go out to work, whereas I work from home. Over the last 12 years I've taken in countless parcels for them, sometimes more than one a day. Certainly coming up to Christmas it was constant. They always thank me and life goes on.
Anyway, their house is up for sale. There's no board up but I've seen it on Right Move. They haven't mentioned it. I know it's none of my business and it's entirely up to them.
However, as we're on friendly terms, if it was us moving I would definitely have told them, just out of courtesy really.
Is it me? In similar circumstances WWYD? i.e. would you tell your neighbours?
