Random pet peeve

When graders say to "expand on something" when everything else in the paper has been stripped down to its bare minimum and you're barely fitting within the alloted length. Where, pray tell, would you like me to expand into?

P.S. It's the first big snowfall of the season. I'm sitting in a cafe, writing about bioethics, and watching big chunky flakes sift down outside. It's been snowing nonstop since early this morning. Winter is most certainly here, and for now--for now--I'm certainly enjoying it.
