The careless husband

Sir Charles Easy, who neglects his wife and carries on an intrigue with her maid Edging and with Lady Graveairs, is eventually moved to reconciliation by her toleration.

First performed and published in 1704, this is exactly what you'd expect of restoration drama, if perhaps a bit simpler than some specimens. It's fun, quick-moving, and has wit & confusion & dirty jokes (of that time) to spare.
