Today I’ve had three different English neighbours drop off Christmas cards to my home in London and not ring the doorbell to do it but just drop it quietly front of the door. Not even the letter box. All three would have known that someone was home as well. Is it normal to be friendly enough to write a Christmas card but to not be friendly enough to want to actually talk to me? I’m not from the UK and find this so bizarre.
Update: Thanks everyone for the replies. The overwhelming consensus is that this is totally normal with some even thinking I am odd for evening asking.
The rationale is less unanimous and is split between, fear of social interaction, performative neighbouring, or fear of disturbing someone.
