Girl code: Will wives ever get the time to rest?

Last weekend, I went to visit a friend of who happens to be married. Just spending a day with her nearly made me change my mind about marriage. Before I even continue, do some married women ever have the option of getting tired in their homes or do they just work round the clock like machines? I thought my three-year-old alone was a handful to me until I spent a weekend in my friend’s house.
