Idea #1: Go On A Picnic
Idea #2: Go For A Drive
Idea #3: Play Board Games
Good old-fashioned board games are still around for good reason- they're freaking fun! Boardgame cafes are popping up all over these days, which is great because now we can enjoy our favorite pastime without having to clean up afterward or buy an expensive collection of pieces every time we want to play something new.
Idea #4: Go To The Local Park
Take a walk through the local park together, have a picnic on one of its many benches, fly kites. Play catch, run around with your dog if you have one. There are infinite things to do at the park that don't cost any money but can bring so much joy to both of your lives.
Scour the house looking for these objects in various rooms before going out for dinner. Give clues when someone is close but not revealing all the answers until they're back from getting ready (you'll need about 20 minutes).
Idea #6: Have A Night In
