I just gave my girls a brand new pack of sidewalk chalk. Usually this lasts them a few weeks, so I was pretty surprised when they came in after only one day of use and said they were out. I went outside expecting to see the usual rainbows and flowers, but there were none to be found. What did I see? My driveway turned into a billboard for social media advertising! I'm beginning to think they may be spending a little too much time online.
