When I went to go out this morning there was a box of chocolates on my doorstep.
When I got home this afternoon there was another box, plus a card, which said inside "merry Christmas love Santa."
AIBU to be a bit freaked out by this? I live in a large block of flats (over 50 flats) so it must be someone in my building.
For full disclosure, this happened a couple of Christmases ago but hasn't happened at all for the last two years.
