Magnifying front door windows - amazing

My drive slopes down. At the bottom is my front door. I parked my car and came inside to make some lunch. A while later I walked past my front door. "Hmm. How come my car looks like it's actually touching my front door? How can the glass have suddenly become magnified?" I genuinely had all those thoughts before realising. I had not put the handbrake on. My car had rolled into my house. We couldn't get out of the front door and had to escape out the back. Sigh.
