When you go to the movie theater, while the movie is playing, tell your sweetie that you have to go to the bathroom. Instead, sneak outside and leave something in or on his car. For example: a card, flowers, putting a tape you made to start when he turns on the car… anything. After the movie is over and you go back to your car, he will find the surprise so act dumb like you don’t know a thing. He’ll love it.
