Quiet night with the wife. My fun days are usually week days when I can work late and then go out with the guys from work. Often on those nights I start out drinking with the guys from work, and end up drinking with the girls that are definately not from my work It's a good cover, and thank god I have a job where it's OK if I don't show up until 10:30am some days the next day.
Weekend nights though tend to be quiet family nights for me. Not always, but usually.
