Greeting cards can be used for a multiplicity of occasions, from birthdays to congratulations to thank-yous. But always remember one rule: do not use a greeting card to articulate an emotion that you cannot verbalise yourself. It is always inappropriate, for example, to send a ‘With Deepest Condolences’ card to someone who is suffering a bereavement; a handwritten, personal note is infinitely more meaningful. It is much better to write a personal note of thanks to a hostess; alternatively you can write a message inside a blank card. If you do choose a card with a customised greeting, ensure that it is appropriate to the occasion and the recipient – be especially careful around the more risqué messages.
