I think I have done much worse in my life, but this is the most recent that came to my mind, it was in August this year.
I was coming back to France - I live in Brazil- after eight months away from my family. There was some suspect package at the airport in Paris so they made us wait for one hour before we could get to the Immigration Check.
The huge room was totally full, maybe one thousand people (the perfect place for a terrorist attack), all desperate to get out and start holidays, see their loved ones or eat some real croissants.
But then came this huge group of young people back from holidays who thought they were smarter than anyone else. They were clearly cheating the line, getting in the front of everybody…and no one was saying anything (French people are so polite!).
At last, one lady stood in the front of one of them : “you stay in the line ! Like everybody else ! “
I wanted so bad to have done the same and was hit by remorse. When one hour after, I eventually got out from Immigration, the whole group was there, waiting for the one that was missing.
I couldn’t help a huge smile, and one of the girl smiled back at me. I told her : “See what you got from cheating ?” And went to the Luggage room.
Felt so good !!
