I have been living in a tourist town for the last 10 years, which means that I often end up on pictures against my will (tourists just photographing stuff I happen to walk in front of). For a little personal revenge, I have developed the following hobby: whenever I walk towards a tourist making a picture of something behind me, I turn to whatever he/she is photographing with a confused look that may be described as: "what on earth is picture-worthy here?". It's fun.
