Finding crazy people is easy and it is only question of sitting outside at a terrace while taking a coffee and watching people around you. For sure that you will find characters who are most taken out of some kind of freaky film than from reality, although they are so real as you are.
It was yesterday when I realized about this situation. I was sitting on a bench feeding pigeons in the park as every day I do, when suddenly a man dressed up as a rabbit appeared running over some children. Quickly I called police who in two minutes where there asking the man about his identity and trying to know more about his intentions.
The man dressed as a rabbit stared at me discovering that I was who had called the police. He went over me shouting that what the hell I was thinking about him, if he was a perverted or something similar. Police calmed the man and carried him to the police station.
I am still in shock, because being witness about something wrong is not guarantee of safety and less when there is a crazy mind over you.
