i cooked dinner, advertised it well in advance to DD and actually cooked it on time for when she said she would be back.
Turns up 20 minutes late, after we'd all finished eating.
So what's the right response?
Pull up a chair and help yourself?
Or
We have finished eating, you were late for dinner, once we've cleared up you can sort your own dinner out of the leftovers.
