After Irene's daughter gets married, she receives a thank you note from Vera, with whom she socialised at the occasion. Touched by the gesture, Irene responds to Vera's note, and so begins a correspondence in which the ladies discourse upon all manner of events in their lives.

The Wedding of Irene's daughter Leslie was a great success, but who was that lady Irene got tiddly with at the reception? It turns out to be Vera - not a relative at all but just helping with the catering - but she's very nicely written to say thank you, so Irene replies to Vera, thanking her for her thank you letter. And they're away. Now that the children are off their hands, Irene & Vera - both widowed - have plenty of time for a correspondence. An exchange of dubious recipes is spiced with increasingly nervy speculation about what they drunkenly got up to at the wedding. Vera is relaxed, but Irene has an eye to her dignity and gets quite prim. This puts Vera in a tiz and she trips over the dog and down the stairs.

Irene is mortified and sends flowers, but that stupid florist gets the order wrong and, anyway, Vera is recuperating on the coast with Audrey Roscoe. Vera's learnt that Audrey is an old friend of Irene's. She hints that Audrey may have been indiscreet about Irene and Irene is tortured by the uncertainty.
