If I accept a parcel for next door , I mostly wait for them to come and get it. I certainly wouldn't rush my shower over it, nor would I wait in until they came round for it. They'll knock again if I'm out.
If it starts to inconvenience you, Pixiel, just decline the parcels. Next door won't know!
Cautionary tale follows.
We experienced a wonderful fiasco once, with a microwave oven. A delivery man from a local Panasonic shop asked me to take it in for Number 10, which I did. He carried it in and put it on the hall floor. The box was enormous for a mere microwave.
Number 10 neighbour duly came for it but was puzzled as she'd not ordered anything. When we tried to lift it, we discovered it weighed a ton - too heavy for her to carry and awkward for two people to carry up her front steps. She left it, saying she'd send her husband over when he got home and they would phone the shop to query it. It must be for someone else in the street.
The husband at number 10 duly removed it. Unfortunately, the shop was shut until the next day .
Next morning, Number 19 came to the door asking for the oven (they'd just come off the phone to the shop, who'd said it was at my house). I told them it was now at Number 10 (who'd gone to work for the day). Number 19 was livid with the shop and left, intending to get blood from someone in the shop (they are a bit like that).
Half an hour later, as we were getting into our car to go out, the original delivery turned up to get the oven from us ! I had to give him the bad news that it was in Number 10's house and he then had to visit Number 19 to make peace.
Number 19 got into a strop and cancelled the order.
