Dear Arnold Den,
Please accept my apology for having to cancel our luncheon on Tuesday. My daughter is visiting unexpectedly and is going through a bit of a rough patch. I hope you’ll understand that I would not feel right leaving her at this time.
I’d love to ring you after her visit to try to reschedule. Take a look at your calendar and we’ll discuss dates then.
I’m looking forward to seeing you again!
