After 32 years of marriage I've worked out that I can get away with anything as long as I put it on the calendar in advance. The Missus just wants to know how much food to buy. I've already got all the Sussex cricket fixtures on the calendar.
If you don't assert yourself now you have many years of resentment ahead of you and your marriage will eventually fail.
Snap! Exactly what I do. If it's on the calendar no argument. See you at the cricket.
