One thing that always irks yet amuses me at the same time is when people express surprise that a robber or thief was "well-dressed and clean-cut". You see this often in forwarded emails that make the rounds. The email writer details how a friend of a friend or sometimes themselves were robbed at knife- or gunpoint and then ends it with a caution and surprise at how normal and un-robber-like the perpetrator looked. 

I'm always amused by how these people express protest that the criminal did not honour the imaginary code to dress like a criminal. 

Evil does not dress in red with a pointy tail and a horn-rimmed head. Ask for the grace to see beyond appearances, to the true nature of a thing - or a person.
