Playing Hooky

I called in sick to work. I've been pretending to be at work in texts to my husband. But right now I an sitting on the edge of a lake on a gorgeous sunny spring day. The lake is almost two hours away from home. I'm just reading my textbooks on my Kindle, nothing nefarious, but I feel sad... Why does a part of me continually rebel against what I ought to be doing? Why do I feel that I must have secrets?
