A left palaver

A couple of months ago, maybe three, we found a pale grey V neck sweater at an empty table.
We dutifully hung it with the lost property.
I have a vague memory (a lot of tea under the bridge since then) of a 'phone call from the owner (Gentleman 1) and it was moved into the staff-coats-hanging-area.
Two or three weeks ago we found another pale grey V neck sweater on the back of a chair in the conservatory. We dutifully hung it with the lost property.
Coincidentally, one day later Gentleman 1 came to retrieve his lost sweater. We gave him sweater 2, having forgotten all about sweater 1. He was really happy. Until his wife pointed out that it wasn't his.  It was a lady's sweater. (Dogs? Sweaters? How is one to tell the difference?)
They had tea in the garden and went home.
And then we found sweater 1, folded neatly, waiting to be collected.

This week gentleman 1 returned for tea and I was thrilled to be able to reunite him with his real, actual sweater. He was SO happy. And incredulous.
He took it outside to his wife on what was a beautiful, sunny, warm afternoon.
I expect the warmth made his wife take off her black cardigan.
Which is why we found it on the back of her chair after they'd left.
