Even have neighbours message me if they know we're away and something gets left visibly on the doorstep or at the back gate.
Yes, we do that too here in my street.
Not everybody has an enclosed porch like me, so if parcels are left exposed to the elements/passers by, next door neighbour will move them to a safe area.
Most of us are out working, some of us are on longer shifts or away on jobs for a couple of days.
We also have a local FB page, sometimes I see people from a few streets further up asking who's got their package, usually they find it.
