There is something to be said for knowing who you are and what you like to do. You like to stay at home. Fine. But you are being totally predictable to your wife and staying in your little box. At home.
Apart from the message it sends to her, changing up your routine may just give you a new perspective on life. As TH says, its a time to explore new things and discover things about yourself that you don't know. Could be fun if you let it.
