I just watched one of those ‘English etiquette guide for foreign visitors’ videos and it mentioned always say thank you when somebody says ‘bless you’ when you sneeze.
I don’t do this 😬 Thinking back to my childhood, the belief on the school yard was that saying thank you ‘cancelled’ the good luck of ‘bless you’. Obviously that is ridiculous but it might explain why it didn’t develop as an automatic habit, though clearly I should have picked this up since.
I think I might mutter a ‘sorry’ after a sneeze, maybe a thank you if the bless you comes from a stranger, but by and large I don’t respond.
Clearly I have been a rude sneezer for the last 37 years!! How unreasonable / rude have I been?
I like to think I am polite in my other interactions
