On a house call I saw both study candlesticks burned down to their stubs, side by side. This house has one kind who can stay up all night and one kind who can't, living under the same roof, and candlelight doesn't tell them apart.

• OsmonI keep the candles well stocked, doctor.
  GrahamThat wasn't quite my point.
• MartaWhat that house spends on candles is what we spend on flour.
  OsmonI keep the flour well stocked too.
