1. Go on a museum date. Art! And staring at things instead of talking.
2. Have dinner and see a movie. Eating food and watching someone tell you stories is a classic for a reason.
3. Take a long walk together. You don't need a destination because you have each other.
4. Go on a picnic. Few things are more romantic than packing up an old-fashioned picnic. If you've never done this, now's the time.
