As much as two people may love each other (like Mr. & Mrs. Skoorbie), I still think there is such thing as having too much time with someone, especially if they both work for the same company/at the same office. Wives need to let their husbands have a "guy's night out" from time to time as husbands need to allow the same.
I know two forum members whose wives let them host LAN parties, which seems ideal to me: guys get together, drink beer, have a barbeque, play games all day, and the wife is right upstairs, not far away.
If and when I do get married, I still think I'll need some alone time at home every once in a while, being the introvert that I am.
