What the...?

Reality ain't what it used to be!

It is strange to watch whole generations adopt something that is "wrong." Take the term 'card shark.' The phrase was originally coined as 'card sharp,' but when I mention this to people they think I've lost my mind.

Or the biblical motto of "an eye for an eye" is usually thought of as justification for vengeance. In reality, as I understand it, the term was a kind of moderating force because before then the usual process was an escalation...you take an eye, we take your life!
