I have still not solved the mystery of who was pounding on our front door in the middle of the night.
I noticed that one of my elderly neighbours had not taken her milk in, and it was well past 1 pm, so I called in on her and had a lovely chat with her & another elderly neighbour who was there.
Sadly, the first neighbour's daughter-in-law died on Wednesday, so I don't think she is quite herself & has been sleeping in later. The other neighbour had already taken her milk in when I arrived.
The first neighbour's daughter-in-law used to help her out a lot. (Actually it was her ex-DIL because her son & DIL were divorced, but the marriage was a long one, and she still referred to her as her DIL.) I told my neighbour (who is in her mid- to late 80s) I'll make sure her rubbish bin gets put out each week, and to ring me if she needs help with something.
Anyway, neighbour is ok but bereaved, good conversation, but still don't know who was pounding on the door in the night - probably just as well we didn't answer the door.
