Having children forced the three of us to give up on much spontaneity, but that might change as they get older. I'm not expecting it, though!
We schedule dates with each other and our lovers. However, within those periods of time we all seem to work on having a certain amount of spontaneous fun. Of course, we all like going out to dinner and a movie ("boy flicks," sci-fi, and thrillers with him; foreign, sci-fi, and art films with her). I do what I can to really focus on my partners during dates, whether that means not talking about the kids, or politics, or family concerns.
