One time my wife and I had several days off together and got kinda bored. We had a ten or fifteen dollar Wal-Mart gift card left over from some unremembered thing and decided to go and spend it on something fun. After wandering the aisles for a while, we decided to return to our roots and go Crayola.
We each chose a coloring book, bought a big box of crayons, some Silly Putty (just for kicks) and returned home to have a very unique evening together. It was fun remembering childhood this way. It gave us time to reminisce and time to just sit and talk about life while doing something relaxing.
