I have no idea. I understand reading the verses on cards that are amusing or entertaining, and even the personalised words written into the card by the card-giver, but the fluffy pre-printed smulsh inside Christmas cards?
Well if we're supposed to be paying attention to and reading the pre-printed verses Christmas cards come with, (either on receiving or before giving a Christmas card) I did not know, and have neglected to do so in the past.
