Activity: Get some chalk and write her a message on the driveway or patio ect.
Luckily I had some kids sidewalk chalk at home so this one was really easy. She left for work about 5 or 10 minutes before me, so after she left I went out and wrote my initials and drew a heart and then her initials. So when she got back home she saw it. She thought it was so sweet and even took a picture of it and posted it on facebook. You can ssee the picture below.
