A Sunday get-together on Monday

We are having our Sunday brunch today; I am contributing my usual fruit salad. Being actors, we couldn't be bothered to get the Sunday brunch together on Sunday. Also, your traditional 'brunch' occurs sometimes before the hour of noon. In general, aside from life-support activities, we do not occur before noon.  Some of us barely occur at all.  So our brunch is really a linner or a dunch.
