Miss Manners: Should guests help clean up, or is that always the host’s job?

Dear Miss Manners: My husband and I hosted a brunch gathering of about 10 people at our home. We offered a wide spread of food and drinks, and we used paper plates and napkins to make cleaning up a little easier — and also because I’m in my third trimester and frankly, the idea of cleaning that many dishes had me feeling exhausted.
