I understand that you can’t always be in for parcels and they don’t even turn up when planned a lot of the time. I also am very happy taking in neighbours parcels and grateful if they take in mine, but I ALWAYS collect them as soon as I am back and get the note/message.
Our neighbours on one side have at least 1 or 2 parcels delivered every day (understandable this time of year) but they never collect them. We see them come home from work at different times in the afternoon and then they are home all eve, but never come and get them.
At first DP or I would take them over and they’d always answer the door and take their parcels but after he took another 2 over Monday I said we should wait for them to come over and get them. Well, there are now 3 parcels clogging up the hallway (2 since Tuesday) and DP just wants to take them over, but I feel like they are being CFs, it’s expected and so we shouldn’t. AIBU?
They are definitely in and I know they are getting notes as the postman always says he’ll pop a note in. Unless their dogs are eating them they must be aware 
The other issue I have is that in the summer a valuable package came for me and they must have taken it in as when I got back at lunchtime, I had a card through the letterbox but the package was just left by the doorway (not even disguised a bit in our front garden) for anyone to see.
So the AIBU I guess (and a boring one at that) is:
YABU - just keep taking them over
YANVU - let them pick them up
..part of me wants to just put them on their doorstep but I won’t be that petty... maybe
