The one word in the English language that people don't like saying, even though it isn't rude. The word that speaks of closed doors, echoes, graves and the tearing of a heart.
Good? Why good? I'm not going to see you again - I'm not going to meet you any other day, so why good? And why 'bye'?
Why can we not bring ourselves to speak it?
Other words are like this. I just don't know why.
