Date Night?

For 5 years now Kendall and I have had date night at least once a week.  Sure, date night is not always steak and potatoes or lavish nights on the town, but we always have a great time.  Recently I was babysitting our newest niece and I told her mom I had a date.  Her response was "is it your anniversary?"  I said "no just date night."  I had no idea 'date night' is unusual.  Kendall and I then came to the conclusion that no matter what we will always have date night and it is not unusual.
