The winter season has begun, there is nothing more to say. It was
proved yesterday evening upon seeing the countless number of pretty women
who were adorning the boxes in the Folies-Bergère. ...Apparently all the
elegant people from the beaches and other watering places had returned to
Paris to celebrate the Isola brothers.
1. On 2 April 1903 Proust was present with Lauris at the re-opening of the Folies-Bergères; he wrote an article in which he gave an account of the evening in a rather whimsical fashion.
See Kolb-Proust ID:C31220 and Corr III, p. 286, n. 3. The source
of Kolb's note is unclear, it is also unclear whether this was by
Proust. And why would the "winter season" begin in April?
