Oh dear, now you have to think about two sets of calibration charges.
Had an interesting conversation the other evening with a young guy (actually quite good looking, nearly as good looking as me) who is married to a real old dragon. Guy owns a bar and is really an extremely friendly and easy going chap, but old bag-wash is never off the phone bitching at him.
The conversation somehow turned to why my wife seemed to tolerate my little habits like drinking beer and fast motorbikes (actually she doesn't tolerate but knows what the other choice is) - as I replied to him, since we've been married my wife has never had to work or consider money, has had everything she wants, never been hungry, if she felt like getting out and giving me the same conditions, then I'd let her drink beer and ride fast motorbikes 
Tell your wife to get out there and change the wheel bearings with no torque wrench while you put a pinny on and knock up egg and chips in the kitchen.
