Why would you call them and not just walk a couple of meters to their door with the parcel?
Unless you live in the middle of nowhere, where "neighbour" means "20 miles away", then realistically you're taking 5 mins of your time at most, and they're likely to return the favour.
Obviously the above doesn't apply if it's something bulky, e.g. furniture, or if they're taking the mick with multiple parcels every day
On the face of it, you make a valid point Haggisman, but there is only one neighbour that I’m ever asked by a courier to take a parcel in for, and like mine, her house is a 3 storey town house, with the lounge and the kitchen-diner area on the first floor.
However, unlike me, she does not have an intercom linked to her front door, plus she broke a couple of bones in her foot a month or so back, and takes forever to descend the stairs if someone knocks on her door.
This would mean that if I took a chance and knocked at her door without first ascertaining that she was in, I could be standing there like a mug in zero degree weather, wondering if a), she’s in, and b), if she is, how bloody long will it take her to get to the ground floor?
So, as my calling plan gives me 750 free minutes, it’s simpler to call her, and leave a message if there’s no answer, okay?
Oh, and not for nothing, and with the best will in the world, my hand to God, it’s metres, not meters, unless you’re American, in which case I apologise.
