We are in the same boat as most, two kids, we work opposite schedules, plus there are always those hidden expenses that come with raising kids.
We get out maybe 1-2 times a year. Never really for special occasions. It is usually that moment when we are comparing schedules and realize, "Wait! I am off and you are off, my parents are in town, and all of the bills are paid, YAY! Date night!" Not sure where everyone is from, but the last date we had we went to a fondue place that was very romantic. We had a dark booth in a corner all to ourselves and he told me about the traditions that follow fondue like if a woman drops her food in it she has to kiss the man and things like that. I have to look them up now, but that made for great foreplay and a very fun evening.
