Our reading
An editorial interpretation.
Revealing an identity is imagined as enough to empty the dinner table. The remark gives a disclosure an immediate social consequence, contrasting the ordinary act of staying for a meal with what knowing the truth might provoke. Its force lies in that prediction, not in a departure actually shown.
