Have a date where you pretend to be private investivators. First, dress in your best “incognito outfits,” i.e. dark shirts, raincoats, toboggans, etc. Next go into a public area where a lot of people walk around. Choose someone you don’t know to keep and eye on and follow them everywhere they go. The game continues until you are spotted, then duck into the nearest restaurant for dinner and debriefing!
Find a secluded, poorly lit spot in the area. Drive there after dark on a clear night. Bring a blanket and something of your favorite delectables and beverages. Lay on top of your car (or on the blanket beside it if you have a sensitive roof). Spend the evening gazing at the stars and constellations. Try to pick out satellites moving slowly through the night, but only make wishes on real shooting stars!
Set up your abode to be a spa. Put out fresh towels and vegetable facial cleansers, along with all the beauty products and lotions you can find. Take turns offering each other all the services of a spa, giving each other massages, facials, and tasty snacks.
Get together at one of your abodes (whichever has a stereo and/or CD burner). Everyone bring a stack of your favorite CDs. Take turns playing one of your favorite songs for each other until you have 13-17 songs. Then make a mix CD of all your collectively favorite songs. Label it with the date of the date and keep it to enjoy whenever you like. (Then make a play-list and put it on your phone...)
Get together at one of your abodes (whichever has the best-stocked fridge). Go through all the food doing blind sensory tests. Blindfold and feed one another, while trying to guess the food first by smell, touch, and then taste. Once you have finished each person picks two items and together you can make a meal.
One Sat drive the long way to a restaurant for lunch. As you drive, look at all the different cars that are on the road and think about which ones you like the best. While you are at lunch, decide the cars that are your favorite (only 1 each). Then, after lunch, go to the car dealerships for each of those cars and take a test drive.
Turn your yard, patio, or driveway into a beach for some fun in the sun. This works well even when it is cold for you polar bears! Get a plastic pool and fill it with sand or water. Put on your sunglasses and Jams, and jam to some beach music while you dangle your toes in the pool and enjoy frozen fun drinks!
