Hi! Here is my contribution:
Look for a nice place where you can sit (a bench, stairs, a platform, etc), and where quite some people are passing by. Take your book and pretend to read, but don't read actually. Instead, watch the people and observe them. Like you are waiting for a friend. Play with your hair from time to time. After five minutes, you may continue with your day.
Oh, and please wear a butt plug while you are doing this.
I am looking forward to read your report
