I was on my way home from a trip to visit my brother. I barely got a chance to see my sister-in-law because she was working the whole time. I got off the plane but had trouble finding where I needed to go for transfers. I wandered around in circles until I finally found the direction of my new departure gate. There was a long line for another security screening. I saw the sign on the glass door to take off your shoes when I realized that that I was walking around in my socks. I had taken my shoes off on the plane but forgot to put them on before getting off. In a panic I asked an old lady at the end of the line who I should ask.
