I put this on Facebook when it happened but never received any decent theories. Maybe the MN hive mind can come up with one.
When my DS was born we revieved some cards and a few gifts in the post over the weeks after his birth. A parcel arrived addressed to him, not handwritten but on a printed label and in a plastic posting bag not a brown envelope, so clearly from a company.
We opened the parcel and it contained a spare part for a particular well-known brand of vaccuum cleaner, and a dairy milk. There was no packing slip, no card, nothing just these two items.
There was an indication on the parcel of a postcode it had come from, after some googling we found a hardware shop with that postcode, which was at the other end of the UK. It's not somewhere we've ever bought something from.
The weird elements are:
My DS was only a few days old and so had only been given the name a matter of days before. It is a very unusual name/combination so not another customer with the same name or anything. Not sure how our address would be in their system anyway.
We have never bought anything from that shop. We don't own that kind of vaccuum cleaner so have never ordered that part, or any other kind of spare part. The shops is hundreds of miles away and is an independent store, not a branch of a larger company.
Why did it have a dairy milk in it? That disappeared very quickly in less mysterious circumstances.
Did someone think that would make a good baby gift? I'm sorry to say it didn't, he's never played with it.
I did phone the shop btw but never got an answer. I also asked on Facebook if any of our friends had somehow accidentally ordered a spare part and had it sent to our son. We checked back and all of the gifts in the post (there had been 3 others I think) were addressed to DH and I or X Family and in any event were wrapped gifts inside a jiffy bag with a hand written address on it.
I sometimes come across it in a drawer and mull over how it could have happened or whether it was for some reason deliberate..?
