We’re talking tradition here, for heaven’s sake. Not literary analysis. Do you consider “Good morning” to be a weather report? - Judith Martin

Your answer to when you will be available should be “You’re so kind to invite us, and we wish we could name a date, but it will have to be after we figure out how to manage seeing relatives and friends whom we feel we have neglected.

If you can’t be kind, at least be vague.”

The customs of courtship vary in time, place and class. But they are always based on the desire to secure the affections of a person one believes to be too perfect to be reasonably attainable, not a person whose most conspicuous characteristic is convenience.
