It’s all about allowing yourself. Either your coworkers/friends join you in being silly and unpredictable, or you get used to getting strange looks. No one ever died from a strange look.

A few weeks ago I was at Lush, and a young lady had goodies she was giving away if you answered a trivia question. She asked if I wanted to play and my response was ‘The answer is 42’.
