"Trafalgar Square"
We entered the National Gallery 30 minutes before closing. We headed immediately to the Vermeer and Leonardo. Before I started this painting I went to the toilet which is under the terrace of the square, and I left my collapsible umbrella beside the basin. When I noticed it I went back to rescue it, and had to spend 20 pence again. But it had gone! After finishing painting, I went to the cleaner and retrieved it. I was shocked to realize that I left several things behind in this trip, not only my umbrella.
