How about playing a round of 'The Newlywed Game' with your spouse or partner tonight? (I really love this one) And for more added fun, if you have kids, have them make up the questions.
Another date night idea that deserves consideration is 'DIY Photoshoot'. If you're like my husband and I there aren't many photos of just the 2 of you. Set aside a day where you'll take lots of photos. ex: cooking together, sitting on the couch, taking a walk, riding bikes
