"...that strength in reserve which is called laziness"

The dispute that goes on between Macbeth and his wife about the murder of Duncan is almost word for word a dispute which goes on at any suburban breakfast-table about something else. It is merely a matter of changing "Infirm of purpose, give me the daggers", into "infirm of purpose, give me the postage stamps" [...]The strengths of the two partners differ in kind. The woman has more of that strength on the spot which is called industry. The man has more of that strength in reserve which is called laziness.
